Abstract

Elevated concentrations of albumin in the urine, albuminuria, are a hallmark of diabetic kidney disease and are associated with an increased risk for end-stage renal disease and cardiovascular events. To gain insight into the pathophysiological mechanisms underlying albuminuria, we conducted meta-analyses of genome-wide association studies and independent replication in up to 5,825 individuals of European ancestry with diabetes and up to 46,061 without diabetes, followed by functional studies. Known associations of variants in CUBN, encoding cubilin, with the urinary albumin-to-creatinine ratio (UACR) were confirmed in the overall sample (P = 2.4 × 10−10). Gene-by-diabetes interactions were detected and confirmed for variants in HS6ST1 and near RAB38/CTSC. Single nucleotide polymorphisms at these loci demonstrated a genetic effect on UACR in individuals with but not without diabetes. The change in the average UACR per minor allele was 21% for HS6ST1 (P = 6.3 × 10–7) and 13% for RAB38/CTSC (P = 5.8 × 10−7). Experiments using streptozotocin-induced diabetic Rab38 knockout and control rats showed higher urinary albumin concentrations and reduced amounts of megalin and cubilin at the proximal tubule cell surface in Rab38 knockout versus control rats. Relative expression of RAB38 was higher in tubuli of patients with diabetic kidney disease compared with control subjects. The loci identified here confirm known pathways and highlight novel pathways influencing albuminuria.

<div type="abstract" xml:lang="en">
<p>Elevated concentrations of albumin in the urine, albuminuria, are a hallmark of diabetic kidney disease and are associated with an increased risk for end-stage renal disease and cardiovascular events. To gain insight into the pathophysiological mechanisms underlying albuminuria, we conducted meta-analyses of genome-wide association studies and independent replication in up to 5,825 individuals of European ancestry with diabetes and up to 46,061 without diabetes, followed by functional studies. Known associations of variants in
<italic>CUBN</italic>
, encoding cubilin, with the urinary albumin-to-creatinine ratio (UACR) were confirmed in the overall sample (
<italic>P</italic>
= 2.4 × 10
<sup>−10</sup>
). Gene-by-diabetes interactions were detected and confirmed for variants in
<italic>HS6ST1</italic>
and near
<italic>RAB38</italic>
/
<italic>CTSC</italic>
. Single nucleotide polymorphisms at these loci demonstrated a genetic effect on UACR in individuals with but not without diabetes. The change in the average UACR per minor allele was 21% for
<italic>HS6ST1</italic>
(
<italic>P</italic>
= 6.3 × 10
<sup>–7</sup>
) and 13% for
<italic>RAB38</italic>
/
<italic>CTSC</italic>
(
<italic>P</italic>
= 5.8 × 10
<sup>−7</sup>
). Experiments using streptozotocin-induced diabetic
<italic>Rab38</italic>
knockout and control rats showed higher urinary albumin concentrations and reduced amounts of megalin and cubilin at the proximal tubule cell surface in
<italic>Rab38</italic>
knockout versus control rats. Relative expression of
<italic>RAB38</italic>
was higher in tubuli of patients with diabetic kidney disease compared with control subjects. The loci identified here confirm known pathways and highlight novel pathways influencing albuminuria.</p>

<abstract>
<p>Elevated concentrations of albumin in the urine, albuminuria, are a hallmark of diabetic kidney disease and are associated with an increased risk for end-stage renal disease and cardiovascular events. To gain insight into the pathophysiological mechanisms underlying albuminuria, we conducted meta-analyses of genome-wide association studies and independent replication in up to 5,825 individuals of European ancestry with diabetes and up to 46,061 without diabetes, followed by functional studies. Known associations of variants in
<italic>CUBN</italic>
, encoding cubilin, with the urinary albumin-to-creatinine ratio (UACR) were confirmed in the overall sample (
<italic>P</italic>
= 2.4 × 10
<sup>−10</sup>
). Gene-by-diabetes interactions were detected and confirmed for variants in
<italic>HS6ST1</italic>
and near
<italic>RAB38</italic>
/
<italic>CTSC</italic>
. Single nucleotide polymorphisms at these loci demonstrated a genetic effect on UACR in individuals with but not without diabetes. The change in the average UACR per minor allele was 21% for
<italic>HS6ST1</italic>
(
<italic>P</italic>
= 6.3 × 10
<sup>–7</sup>
) and 13% for
<italic>RAB38</italic>
/
<italic>CTSC</italic>
(
<italic>P</italic>
= 5.8 × 10
<sup>−7</sup>
). Experiments using streptozotocin-induced diabetic
<italic>Rab38</italic>
knockout and control rats showed higher urinary albumin concentrations and reduced amounts of megalin and cubilin at the proximal tubule cell surface in
<italic>Rab38</italic>
knockout versus control rats. Relative expression of
<italic>RAB38</italic>
was higher in tubuli of patients with diabetic kidney disease compared with control subjects. The loci identified here confirm known pathways and highlight novel pathways influencing albuminuria.</p>

<title>Introduction</title>
<p>Urinary albumin and serum creatinine are two biomarkers recommended for the routine assessment of chronic kidney disease (CKD) (
<xref rid="B1" ref-type="bibr">1</xref>
). Even at physiological rates of glomerular filtration, small elevations in urinary albumin concentrations are associated with an increased risk for CKD progression, end-stage renal disease (ESRD), cardiovascular events, and cardiovascular and all-cause mortality (
<xref rid="B2" ref-type="bibr">2</xref>
<xref rid="B4" ref-type="bibr">4</xref>
). Patients with diabetes are at a particularly high risk for CKD and its sequelae: the prevalence of CKD among individuals with diabetes is >40% compared with ∼10% in the general U.S. adult population (
<xref rid="B5" ref-type="bibr">5</xref>
), and the presence of CKD is an important contributor to the excess mortality in diabetes (
<xref rid="B6" ref-type="bibr">6</xref>
). The appearance of significant amounts of albumin in the urine (albuminuria) is a hallmark of diabetic kidney disease (DKD), the incidence of which continues to rise along with type 2 diabetes worldwide (
<xref rid="B7" ref-type="bibr">7</xref>
). Residual diabetes-related microvascular risk represents an important challenge even in treated individuals (
<xref rid="B8" ref-type="bibr">8</xref>
), and DKD remains the leading cause of ESRD. No new effective treatments for DKD have been approved in more than two decades (
<xref rid="B9" ref-type="bibr">9</xref>
), highlighting the importance to better understand its underlying mechanisms.</p>
<p>Using genome-wide association study (GWAS) meta-analysis in general population cohorts, we previously identified a missense single nucleotide polymorphism (SNP) in the gene encoding cubilin (
<italic>CUBN</italic>
) in association with the urinary albumin-to-creatinine ratio (UACR) (
<xref rid="B10" ref-type="bibr">10</xref>
).
<italic>CUBN</italic>
is currently the only genome-wide significant locus for UACR. However, this variant explains only a small fraction of the previously reported heritability of albuminuria, ranging from 0.2 to 0.46 in the general population and in those with diabetes (
<xref rid="B11" ref-type="bibr">11</xref>
<xref rid="B13" ref-type="bibr">13</xref>
), suggesting that additional genetic variants remain to be found. Here we report the results of a GWAS meta-analysis of albuminuria traits in the general population performed in almost twice the sample size of our previous study (
<xref rid="B10" ref-type="bibr">10</xref>
), with a special focus on those with diabetes, replication in additional independent individuals, and follow-up investigations in human tissues and a genetically modified animal model of diabetes.</p>

<title>Study Populations</title>
<p>Our study was based on 30 discovery and replication studies mostly from the general population, with the exception of Action in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation (ADVANCE) and Genetics of Diabetic Nephropathy (GENDIAN), which enrolled exclusively individuals with type 2 diabetes, totaling 67,452 participants of European ancestry across the different analyses (up to 7,787 with diabetes in discovery and replication). The study characteristics, including the distribution of albuminuria and diabetes, are reported in
<ext-link ext-link-type="uri" xlink:href="http://diabetes.diabetesjournals.org/lookup/suppl/doi:10.2337/db15-1313/-/DC1">Supplementary Table 1</ext-link>
. Study protocols were approved by each local institutional review board or ethics committee, and all human participants gave written informed consent.</p>

<title>Phenotype Definitions and Analytical Strategy</title>
<p>The measurement of urinary albumin and creatinine in each study is reported in
<ext-link ext-link-type="uri" xlink:href="http://diabetes.diabetesjournals.org/lookup/suppl/doi:10.2337/db15-1313/-/DC1">Supplementary Table 2</ext-link>
. Urinary albumin values below the detection limit of the used assays were set to the lower limit of detection. Rather than using urinary albumin, the UACR was calculated as urinary albumin/urinary creatinine (mg/g) to account for differences in urine concentration. Microalbuminuria (MA) was defined as UACR >25 mg/g in women and >17 mg/g in men (
<xref rid="B10" ref-type="bibr">10</xref>
). Diabetes was defined as fasting glucose ≥126 mg/dL, nonfasting glucose ≥200 mg/dL, or treatment for diabetes, or by self-report if this information was not available. Across studies, we evaluated two traits, UACR and MA, and performed four GWAS meta-analyses: MA and UACR in the overall sample, as well as UACR—a continuous trait with higher statistical power—separately among those with and without diabetes. Diabetes-stratified genome-wide association analyses of MA were not performed due to limited sample size. Detailed information on the design, genotyping, imputation, and data management of each study is provided in
<ext-link ext-link-type="uri" xlink:href="http://diabetes.diabetesjournals.org/lookup/suppl/doi:10.2337/db15-1313/-/DC1">Supplementary Tables 2 and 3</ext-link>

<title>Discovery Meta-Analysis, Replication, and Power</title>
<p>Stringent quality control of the genetic data was performed at the individual study level and again at the meta-analysis level using state-of-the-art methods. Missing genotypes were imputed using the HapMap reference panels in 19 studies and the 1000 Genomes reference panels in two studies. Details of genotyping, imputation software, reference panels, and quality filters in each study are reported in
<ext-link ext-link-type="uri" xlink:href="http://diabetes.diabetesjournals.org/lookup/suppl/doi:10.2337/db15-1313/-/DC1">Supplementary Table 3</ext-link>
.</p>
<p>All GWAS were performed following a standardized analysis protocol. In each study, the natural logarithm of UACR was taken. Subsequently, sex-specific residuals were obtained from linear regression models of ln (UACR) on age and study-specific covariates, including study center and genetic principal components, to adjust for possible population stratification, if applicable. The continuous sex-specific residuals were then combined and used as the dependent variable that was regressed on imputed allelic dosages for each SNP in the GWAS.</p>
<p>Before the meta-analyses, all study-specific GWAS summary files underwent quality control using the GWAtoolbox (
<xref rid="B14" ref-type="bibr">14</xref>
). Genomic-control (GC) (
<xref rid="B15" ref-type="bibr">15</xref>
) correction was applied when the GC factor was >1. Inverse variance weighted fixed-effects meta-analyses were conducted using METAL (
<xref rid="B16" ref-type="bibr">16</xref>
). The
<italic>I</italic>
<sup>2</sup>
statistic was used to evaluate between-study heterogeneity (
<xref rid="B17" ref-type="bibr">17</xref>
). All meta-analyses were performed in duplicate by two independent researchers.</p>
<p>After meta-analysis, SNPs with average minor allele frequency (MAF) <0.01 were excluded, and another GC correction was applied. There were 2,191,945 SNPs with average MAF >0.05 and present in >50% of the studies, which were then clustered based on correlation (linkage disequilibrium pruning using
<italic>r</italic>
<sup>2</sup>
≤ 0.2) with the respective index SNP (the SNP with the lowest
<italic>P</italic>
value) within windows of ± 1 MB to identify independent SNPs with suggestive association (
<italic>P</italic>
< 10
<sup>−5</sup>
) in one or more of the four analyses.</p>
<p>Replication testing was then performed for signals that were genome-wide significant (
<italic>P</italic>
< 5 × 10
<sup>−8</sup>
) in any analysis or that showed suggestive association among those with diabetes, motivated by the clinical importance of DKD and the stronger association of the known and validated
<italic>CUBN</italic>
variant on UACR among those with diabetes (
<xref rid="B18" ref-type="bibr">18</xref>
). Replication was defined as a one-sided
<italic>P</italic>
value <0.05 in the meta-analysis of independent replication studies. Five of the nine studies that contributed to replication used imputed dosage, and four studies performed replication genotyping of the index SNPs. A meta-analysis of the replication results was performed. The double GC-corrected results from the discovery meta-analysis and the results of the nine replication studies were meta-analyzed to obtain the overall statistical significance. Unless stated otherwise, all reported
<italic>P</italic>
values are two-sided.</p>
<p>Assuming that associated SNPs explain a respective 0.6% and 0.5% of the UACR variance in diabetes (
<xref ref-type="table" rid="T1">Table 1</xref>
), there was 95% and 91% power, respectively, to replicate the seven suggestive loci from the discovery stage in an additional 1,800 samples with a one-sided
<italic>P</italic>
value of <0.05.</p>

<p>Replicated SNPs were further evaluated even in the absence of genome-wide significance because, in addition to the significant replication
<italic>P</italic>
value, the low heterogeneity across cohorts and the biological plausibility of the

locus further increased confidence in the findings. The SNPs were evaluated in the Diabetes Control and Complications Trial (DCCT)/Epidemiology of Diabetes Interventions and Complications (EDIC) study for association with a primary clinical end point defined as time from the DCCT baseline until time to persistent MA or a secondary end point of time to incident albumin excretion rate >300 mg/24 h or ESRD (
<xref rid="B10" ref-type="bibr">10</xref>

<p>Paraffin blocks of rat kidney samples were sectioned (6-μm thickness) with a Leica RM2255 rotary microtome (Thermo-Fisher Scientific, Waltham, MA) on Superfrost Plus glass slides (12-550-15, Thermo-Fisher Scientific). Before staining, slides were deparaffinized in changes of CitriSolv (22-143-975, Thermo-Fisher Scientific) and 70% isopropanol. Antigen retrieval was accomplished by incubating in sodium citrate buffer (1.8% 0.1 mol/L citric acid, 8.2% 0.1 mol/L sodium citrate, in distillated water, pH 6.0) in a rice cooker for 30 min. Slides were blocked with PBS blocking buffer (1% BSA, 0.2% nonfat dry milk in PBS) for 30 min and stained with primary antibodies specific for megalin or cubilin diluted in blocking buffer overnight at 4°C. Sheep anti-megalin and rabbit anti-cubilin were provided by Dr. P. Verroust, INSERM, Paris, France. After two washes in 0.1% Tween 20 (v/v in PBS), slides were incubated with corresponding fluorophore-conjugated secondary antibodies (Invitrogen), diluted in blocking buffer at room temperature for 1 h, and counterstained with 10 μmol/L Hoechst 33342 (Molecular Probes-Invitrogen, H1399).

KO and transgenic rats have confirmed its role in albuminuria in FHH rats and highlighted a role in tubular albumin reuptake (

). We thus examined these animals in the setting of diabetes as outlined in

. Injection of STZ in 9-week-old rats successfully induced diabetes in all strains (

). Blood glucose rose from normal values before injection of STZ (congenic, 205 ± 3 mg/dL; transgenic, 227 ± 11 mg/dL; KO, 198 ± 7 mg/dL) to high values that indicate severe hyperglycemia 1 week after STZ (congenic, 422 ± 35 mg/dL; transgenic, 406 ± 27 mg/dL; KO, 420 ± 21 mg/dL). Blood glucose levels remained high at age 11, 12, and 13 weeks and showed no significant differences among strains (
<xref ref-type="fig" rid="F3">Fig. 3

). There were no significant differences in mean arterial blood pressure among congenic, transgenic, and KO animals freely moving around the cage. All animal strains showed a tendency toward decreased blood pressure 3–4 weeks after injection of STZ (

KO animals showed a progressive increase in urinary albumin excretion that became statistically significant 2 weeks after injection of STZ. At 4 weeks after injection,
<italic>Rab38</italic>
KO animals had an albumin excretion of 79 ± 14 mg/day, whereas albumin excretion was only 28 ± 8 mg/day in transgenic (
<italic>P</italic>
< 0.01) and 41 ± 13 mg/day in congenic animals (
<italic>P</italic>
< 0.01). These data indicate that diabetic rats without Rab38 are more susceptible to the development of albuminuria than congenic and transgenic animals with functional
<italic>Rab38</italic>
despite a similar degree of hyperglycemia in all animals. Kidney sections obtained from a subset of animals showed a higher average glomerulosclerosis score (2.9 ± 0.3) compared with congenic (2.2 ± 0.1) and transgenic (2.2 ± 0.1) rats (

), but differences were subtler than those observed for urinary albumin excretion.</p>
<p>To further clarify how loss of
<italic>Rab38</italic>
may lead to albuminuria, we performed immunohistochemistry staining of megalin and cubilin, known to mediate albumin reuptake in the proximal tubulus, in kidney sections of all three animal strains. Cubilin and megalin were markedly reduced at the luminal membrane of proximal tubular cells in
<italic>Rab38</italic>
KO rats compared with congenic and transgenic control animals (
<xref ref-type="fig" rid="F3">Fig. 3

), consistent with a role of Rab38 in regulating the abundance of cubilin and megalin at the cell surface. In contrast, there was no significant difference in the number of structures positive for the lysosomal marker LAMP1 among the three strains.</p>

<title>Discussion</title>
<p>In this GWAS discovery meta-analysis of 2,191,945 SNPs in up to 54,450 participants of 20 studies, we replicated the association of the previously identified
<italic>CUBN</italic>
locus and UACR as well as MA at genome-wide significance and identified several suggestive signals among individuals with diabetes. Two of these loci,
<italic>RAB38/CTSC</italic>
and
<italic>HS6ST1</italic>
, showed evidence of independent replication, and
<italic>RAB38</italic>
was further supported by functional studies in a rat model. Our findings point to mechanisms in renal handling of albumin that associate with albuminuria in humans in the setting of diabetes. They thus represent examples of gene-by-diabetes interactions resulting in a complex trait that manifests when environmental exposure and genetic susceptibility variants occur together (
<xref rid="B29" ref-type="bibr">29</xref>
).</p>
<p>Not all individuals with diabetes develop DKD, suggesting that neither the presence of hyperglycemia nor genetic variants alone are sufficient to elicit the renal damage that typically manifests itself as albuminuria in diabetes. Our observations therefore raise the question of how the diabetic environment may result in the manifestation of genetic effects on albuminuria. The lack of association between both genetic variants and type 2 diabetes or specific glycemic measures in humans indicates that their effects occur without influencing diabetes per se
<italic>.</italic>
This notion is further substantiated by the fact that diabetic
<italic>Rab38</italic>
KO rats showed higher urinary albumin concentrations compared with controls despite the presence of similar blood glucose concentrations.</p>
<p>A difference between our observations in humans and rats is that the effect of genetic variation near
<italic>RAB38</italic>
on albuminuria was only found in humans with but not without diabetes, whereas
<italic>Rab38</italic>
KO rats without diabetes also progress to albuminuria (
<xref rid="B22" ref-type="bibr">22</xref>
). A potential explanation is that KO rats represent a null mutation, allowing for the genetic component to take full effect without needing further aggravation by environmental factors. Conversely, many human susceptibility variants of complex traits do not result in a complete loss of function but instead are of a regulatory nature. The effect of such variants may become apparent only upon an environmental challenge, such that genetically determined alterations in renal albumin handling could manifest themselves in the setting of hyperglycemia and/or diabetes due to a number of mechanisms that secondarily affect albumin reabsorption, including an increased load of filtered albumin due to hyperfiltration or impairment of the glomerular filter. Along these lines, our observation of significantly higher
<italic>RAB38</italic>
transcript abundance in tubuli of DKD patients than control subjects may indicate an adaption of the tubular machinery for albumin reabsorption in this setting. Moreover, genetics effects of the index SNP at the
<italic>CUBN</italic>
locus on albuminuria were four times as large in individuals with diabetes compared with those without diabetes, supporting alterations of tubular albumin handling in the setting of diabetes.</p>
<p>
<italic>RAB38</italic>
encodes a member of the small Rab GTPase protein family that regulates intracellular vesicle trafficking between organelles and is important in exo-, endo-, and transcytosis (
<xref rid="B30" ref-type="bibr">30</xref>
). Expression of Rab38 at the mRNA and protein level was observed in proximal tubule cells of wild-type rats (
<xref rid="B31" ref-type="bibr">31</xref>
). FHH rats, a natural
<italic>Rab38</italic>
-null mutation, show increased urinary albumin excretion without changes in glomerular permeability (
<xref rid="B21" ref-type="bibr">21</xref>
). In these animals, the expression of a Brown Norway
<italic>Rab38</italic>
transgene led to phenotypic rescue, and knockdown of
<italic>Rab38</italic>
in a proximal tubule cell system significantly decreased albumin endocytosis (
<xref rid="B22" ref-type="bibr">22</xref>
). Together, these observations support an important role for the small Rab GTPase RAB38 in the reabsorption of filtered albumin.</p>
<p>Impaired RAB38 function may lead to increased albumin excretion via different mechanisms: altered intracellular vesicle transport may affect albumin reabsorption or recycling of reabsorbed albumin back to the plasma membrane (
<xref rid="B32" ref-type="bibr">32</xref>
). Alternatively, altered RAB38 function may affect the delivery of proteins required, such as cubilin or megalin, for albumin endocytosis, the mechanism underlying albuminuria in Dent disease (
<xref rid="B33" ref-type="bibr">33</xref>
). Our experimental data showing reduced abundance of cubilin and megalin in
<italic>Rab38</italic>
KO but not in control rats are consistent with the latter hypothesis. Finally, that impaired RAB38 function may directly cause glomerular damage, in turn leading to increased concentrations of urinary albumin, is also conceivable.</p>
<p>Although the combined evidence from
<italic>Rab38</italic>
KO rats along with the gene expression and GWAS data strongly implicate
<italic>RAB38</italic>
as the gene underlying albuminuria in humans, the intergenic index SNP mapped upstream of
<italic>RAB38</italic>
and downstream of
<italic>CTSC</italic>
and was associated with transcript levels of both genes in whole blood. We can therefore not exclude the possibility that
<italic>CTSC</italic>
may be the causal gene underlying the observed associations or that it contributes to the phenotype in addition to
<italic>RAB38</italic>
.
<italic>CTSC</italic>
encodes for a lysosomal cysteine protease. Rare mutations in the gene cause autosomal-recessive Papillon-Lefèvre syndrome. No renal abnormalities have been reported in affected patients (
<xref rid="B34" ref-type="bibr">34</xref>
),
<italic>Ctsc</italic>
KO mice do not show kidney abnormalities (
<xref rid="B35" ref-type="bibr">35</xref>
), and the gene has not been linked to albuminuria or kidney disease.</p>
<p>The other genomic locus associated with albuminuria in diabetes contains
<italic>HS6ST1</italic>
, encoding the enzyme heparan sulfate (HS) 6-
<italic>O</italic>
-sulfotransferase that catalyzes the 6-
<italic>O</italic>
-sulfation of HS and heparin (
<xref rid="B36" ref-type="bibr">36</xref>
,
<xref rid="B37" ref-type="bibr">37</xref>
). HS are anionic side chains of HS proteoglycans, which are components of basement membranes, extracellular matrix, and cell surfaces. Several studies have reported that inactivation or removal of HS leads to proteinuria, and biopsy specimens from patients with diabetes revealed changes in HS sulfation patterns compared with control subjects (
<xref rid="B38" ref-type="bibr">38</xref>
). Thus, a genetic variant altering the activity or abundance of the enzyme may lead to altered albuminuria. The underlying mechanisms could be manifold, because HS has been reported to affect not only glomerular filtration but also growth factor signaling, composition, and functions of the glomerular basement membrane as well as functions at the endothelial surface layer (
<xref rid="B38" ref-type="bibr">38</xref>
) and the proximal tubule (
<xref rid="B39" ref-type="bibr">39</xref>
).</p>
<p>Strengths of our study include its large sample size, specific examination of individuals with diabetes, and consistent effects across a variety of studies underscoring the relevance of our findings at the general population level. In addition, we performed careful characterization of a replicated finding through in vivo experiments in
<italic>RAB38</italic>
KO and control rats that cannot, however, elucidate the exact mechanism by which genetic variation at this locus influences albuminuria in humans.</p>
<p>Limitations include the fact that the replicated SNPs did not achieve genome-wide significance, necessitating future confirmation in even larger studies, and that we could not assess allele-specific gene expression in human kidney tissues. We focused on European ancestry study participants and mostly on individuals with type 2 diabetes. Future studies should therefore examine these associations among individuals of additional ancestries and in well-powered studies of patients with type 1 diabetes. Although results were combined after study-specific analyses, biological variation in UACR and different urine collection and storage methods may have resulted in increased variation and thus reduced statistical power to reveal significant associations.</p>
<p>Additional studies are required to determine the causal variants and the exact underlying molecular mechanism by which genetic variation at
<italic>RAB38</italic>
/
<italic>CTSC</italic>
and
<italic>HS6ST1</italic>
associates with albuminuria in humans. An elucidation of the underlying mechanisms and the contributions and differences of albuminuria of glomerular and tubular origin may improve our understanding of proteinuric kidney diseases in general but may be especially relevant to DKD, the most common cause of ESRD.</p>
