<front><div type="abstract" xml:lang="en"><sec><title>Background/Aims</title>
<p>Calcium homeostasis requires regulated cellular and interstitial systems interacting to modulate the activity and movement of this ion. Disruption of these systems in the kidney results in nephrocalcinosis and nephrolithiasis, important medical problems whose pathogenesis is incompletely understood.</p>
</sec>
<sec><title>Methods</title>
<p>We investigated 25 patients from 16 families with unexplained nephrocalcinosis and characteristic dental defects (amelogenesis imperfecta, gingival hyperplasia, impaired tooth eruption). To identify the causative gene, we performed genome-wide linkage analysis, exome capture, next-generation sequencing, and Sanger sequencing.</p>
</sec>
<sec><title>Results</title>
<p>All patients had bi-allelic <italic>FAM20A</italic>
mutations segregating with the disease; 20 different mutations were identified.</p>
</sec>
<sec><title>Conclusions</title>
<p>This au-tosomal recessive disorder, also known as enamel renal syndrome, of <italic>FAM20A</italic>
causes nephrocalcinosis and amelogenesis imperfecta. We speculate that all individuals with biallelic <italic>FAM20A</italic>
mutations will eventually show nephrocalcinosis.</p>

<abstract><sec><title>Background/Aims</title>
<p>Calcium homeostasis requires regulated cellular and interstitial systems interacting to modulate the activity and movement of this ion. Disruption of these systems in the kidney results in nephrocalcinosis and nephrolithiasis, important medical problems whose pathogenesis is incompletely understood.</p>
</sec>
<sec><title>Methods</title>
<p>We investigated 25 patients from 16 families with unexplained nephrocalcinosis and characteristic dental defects (amelogenesis imperfecta, gingival hyperplasia, impaired tooth eruption). To identify the causative gene, we performed genome-wide linkage analysis, exome capture, next-generation sequencing, and Sanger sequencing.</p>
</sec>
<sec><title>Results</title>
<p>All patients had bi-allelic <italic>FAM20A</italic>
mutations segregating with the disease; 20 different mutations were identified.</p>
</sec>
<sec><title>Conclusions</title>
<p>This au-tosomal recessive disorder, also known as enamel renal syndrome, of <italic>FAM20A</italic>
causes nephrocalcinosis and amelogenesis imperfecta. We speculate that all individuals with biallelic <italic>FAM20A</italic>

<body><sec id="sec1_1"><title>Introduction</title>
<p>Nephrocalcinosis (NC), diagnosed by radiographs, CT, or increased echogenicity on ultrasound, represents an important renal complication because it can accompany progressive deterioration of glomerular function or nephrolithiasis [<xref ref-type="bibr" rid="B1">1</xref>
]. In some cases, NC provides a clue to an underlying genetic disorder such as hyperoxaluria or distal renal tubular acidosis with or without deafness [<xref ref-type="bibr" rid="B2">2</xref>
,<xref ref-type="bibr" rid="B3">3</xref>
]. In other cases, NC is a side effect of chronic treatment with various drugs, including loop diuretics and vitamin D. In general, the pathogenesis of NC has not been adequately elucidated, although hypercalciuria appears to be a common finding.</p>
<p>Often, rare genetic diseases reveal previously unrecognized mechanisms of action regarding physiology, cell biology, and metabolism. Here, we present genetic studies into a rare human disease of NC combined with amelogenesis imperfecta (AI), a disorder of abnormal enamel formation and impaired tooth eruption.</p>
</sec>
<sec sec-type="methods" id="sec1_2"><title>Methods</title>
<p>Patients and families were identified in our rare disease renal tubular or dental/craniofacial reference centers and gave informed consent. This study was approved by the institutional review boards and ethics committees of the various centers. All patients had NC confirmed by either ultrasound, X-ray or CT, and all showed characteristic teeth findings with AI and delayed or missing tooth eruption.</p>
<p>In short, multipoint parametric linkage analysis utilizing 2,000 highly polymorphic markers (DeCode, Iceland) across the whole genome in 4 informative families as well as homozygosity mapping for another consanguineous family was used to determine the locus linked to this trait, as published before [<xref ref-type="bibr" rid="B4">4</xref>
,<xref ref-type="bibr" rid="B5">5</xref>
]. Next-generation sequencing using exome capture (Perkin Elmer, USA; Leeds Translational Genomics Unit, UK) was performed on 5 patients from 5 unrelated families; 4 were part of the linkage analysis. Subsequent data analysis was restricted to novel sequence variants within the linked region. The frequency of each variant was examined in >100 ethnically matched alleles available in public databases (1000 Genomes, release 12 – May 2012). Sanger sequencing was performed as described, and mutations were sequenced in family members for segregation analysis.</p>
<p>In detail, genomic DNA was isolated from peripheral blood lymphocytes for all subjects using standard protocols. Genotypes from polymorphic markers for 4 families were generated by DeCode, Iceland. Analyses were carried out as published before with modifications [<xref ref-type="bibr" rid="B4">4</xref>
]. In short, genotypes were examined using a multipoint parametric linkage analysis and haplotype reconstruction was performed via Allegro and Genehunter for an autosomal recessive model with complete penetrance, disease allele frequency of 0.001 (DeCode map with appropriate allele frequencies). The data were formatted using Mega2 (version 4.0) through Alohomora (version 0.30, Win32); non-informative markers were filtered out. Mendelian inconsistencies were checked using PedCheck (version 1.1); unlikely genotypes were identified and filtered using Merlin (version 1.1 alpha 3). The Allegro haplotype output files were visualized with Haplopainter. In addition and in parallel, whole-genome SNP microarray analysis was performed on genomic DNA for another consanguineous family by AROS Applied Technology; resulting data were analyzed using IBD finder software [<xref ref-type="bibr" rid="B5">5</xref>
]. Whole-exome sequencing was performed using 3 μg of genomic DNA, which was sheared and ligated to Illumina adapters, according to Agilent's SureSelect Library Prep protocol. The sample was then size selected (200-300 bp) by agarose gel electrophoresis and enriched for 12 cycles, using PCR prior to hybridization to the SureSelect reagent for 24 h at 65°C. The library was denatured using NaOH and diluted to a concentration of 12 pM, of which 120 μl was hybridized onto a v5 single-read flow cell (Illumina, San Diego, Calif., USA). Samples were prepared for sequencing according to Illumina's standard amplification, linearization, blocking and primer hybridization protocols. The flow cell was then loaded onto an Illumina GAIIx and sequencing performed for 80 cycles after which the raw data were processed using the Illumina pipeline. The data (qseq) files generated were aligned to the human reference sequence (hg19/GRCh37) using Novoalign short-read alignment software (Novocraft Technologies, Selangor, Malaysia). Duplicate reads and reads mapping to multiple locations were excluded from any analysis. SAMtools and the Genome Analysis Toolkit were used to further process the alignment files for variant calling [<xref ref-type="bibr" rid="B6">6</xref>
,<xref ref-type="bibr" rid="B7">7</xref>
].</p>
<p>For confirmation of variants detected by exome capture/next-generation sequencing and for mutation detection in additional cases, we amplified all coding exons and exon-intron boundaries of <italic>FAM20A</italic>
using standard PCR methodology with intronic (genomic) primers. PCR products were separated on 1% agarose gels with ethidium bromide using electrophoresis and visualized under UV light. Specific bands were cut and DNA was isolated and purified using standard procedures. Bi-directional sequencing of all exons and exon-intron boundaries were performed using a Beckman Coulter CEQ8000 or an Applied Biosystems 3130xl capillary sequencer per the manufacturer's protocol. Sequencing data was analyzed and compared with the published reference sequence for <italic>FAM20A</italic>
(NG_029809, April 2012, NCBI build 37.3).</p>
</sec>
<sec sec-type="results" id="sec1_3"><title>Results</title>
<p>We ascertained 25 patients (12 males, 13 females; age 12-64) in 16 families with NC and characteristic dental findings, i.e., the triad of AI, gingival thickening and impairment of tooth eruption (table <xref ref-type="table" rid="T1">1</xref>
). The diagnosis of NC was made predominantly by nephrologists based upon characteristic imaging findings. Generalized hypoplastic AI was evident from eruption of the deciduous teeth early in childhood with subsequent impaired eruption of the permanent teeth and development of gingival enlargement. Clinical details of some patients have been published [<xref ref-type="bibr" rid="B8">8</xref>
,<xref ref-type="bibr" rid="B9">9</xref>
,<xref ref-type="bibr" rid="B10">10</xref>
,<xref ref-type="bibr" rid="B11">11</xref>
]. None of the parents or offspring of our patients had AI.</p>
<p>From the 16 families with this disorder, we selected four informative families (fig. <xref ref-type="fig" rid="F1">1</xref>
A) for whole-genome parametric multipoint linkage studies. Using dense (2 cM) polymorphic markers, we identified a single linked locus on chromosome 17q24 with a LOD score of 3.1 (fig. <xref ref-type="fig" rid="F1">1</xref>
B). Haplotype reconstruction placed the locus between flanking markers D17S1821 (97.3 cM) and D17S1797 (106.2 cM), a region of 5.3 million bases containing 41 annotated genes (NCBI build 37.3, October 2011). Independently, homozygosity mapping identified the same locus in another consanguineous family (data not shown).</p>
<p>To identify the disease-causing gene, we performed massive parallel sequencing using exome capture on 5 unrelated patients. Using an autosomal recessive model, limiting our analysis to the linked region, and filtering variants to eliminate common polymorphisms, we found homozygous or compound heterozygous mutations in all 5 patients in only one gene, <italic>FAM20A</italic>
. A total of 20 different mutations (deletions, insertions, and splice site, missense and nonsense mutations) were identified in the homozygous or compound heterozygous state, confirmed by Sanger sequencing, and demonstrated to -segregate with the disorder in our 16 families (table <xref ref-type="table" rid="T1">1</xref>
). <italic>FAM20A</italic>
(cDNA 1,626 bp, protein 541 amino acids, 11 coding exons) is a member of a family of kinase-encoding genes that includes <italic>FAM20B</italic>
and <italic>FAM20C</italic>
.</p>

<sec sec-type="discussion" id="sec1_4"><title>Discussion</title>
<p>Calcium plays many critical roles in human physiology, serving as an intracellular messenger, an extracellular neuromuscular excitatory ion, and a structural component of bone and teeth. For example, tooth enamel (calcium hydroxyapatite) is the hardest human tissue and can function into old age, despite being the only mineralized tissue with no capacity for cellular repair. Hence, the temporo-spatial concentration of calcium must be exquisitely regulated in different compartments, bound to albumin within the circulation, sequestered by calbindin within cells, including teeth [<xref ref-type="bibr" rid="B12">12</xref>
], and excreted under tight control by the kidney [<xref ref-type="bibr" rid="B13">13</xref>
]. Within the vasculature, calcium availability is closely modulated by an intricate interplay between bones and regulatory hormones that involves positive and negative feedback mechanisms (e.g., vitamin D, PTH, calcitonin) [<xref ref-type="bibr" rid="B14">14</xref>
,<xref ref-type="bibr" rid="B15">15</xref>
]. Consequences of dysregulated calcium homeostasis include nephrolithiasis and NC, i.e., precipitation of calcium in the urinary collecting system and renal interstitium, respectively.</p>
<p>The processes that normally maintain calcium balance in renal tissues can be delineated by studying genetic disorders involving NC. A prime example lies in an autosomal recessive disorder of NC combined with AI. Linkage analysis and focused exome sequencing performed on affected families identified the causative gene as <italic>FAM20A</italic>
, previously associated only with a disorder of AI [<xref ref-type="bibr" rid="B16">16</xref>
,<xref ref-type="bibr" rid="B17">17</xref>
].</p>
<p>Previous causes of NC have involved epithelial and paracellular disturbances in calcium transport, predominantly caused by mutations in calcium-specific channels and proteins [<xref ref-type="bibr" rid="B18">18</xref>
,<xref ref-type="bibr" rid="B19">19</xref>
,<xref ref-type="bibr" rid="B20">20</xref>
]. These systems either reabsorb filtered calcium from the filtrate (urine) across the renal tubular cell or release calcium from the tubular cell into the interstitial compartment. When they malfunction, increased urinary calcium precipitates within the renal tubule (leading to nephrolithiasis and urolithiasis) or within the interstitium (leading to NC); this is invariably accompanied by hypercalciuria.</p>
<p>Our 25 patients exhibited NC and AI, but ascertainment of other patients with biallelic <italic>FAM20A</italic>
mutations will expand the phenotype and define the entire spectrum of this rare disease. Also, two different <italic>Fam20a</italic>
knock-out mouse models exhibited different findings; in one, no kidney findings were reported, whereas the other showed arterial calcification without NC [<xref ref-type="bibr" rid="B21">21</xref>
,<xref ref-type="bibr" rid="B22">22</xref>
]. The patients previously reported with <italic>FAM20A</italic>
mutations and AI may also prove to have NC.</p>
</sec>
<sec sec-type="Conclusions" id="sec1_5"><title>Conclusions</title>
<p>Our findings have implications for diagnosis and treatment. FAM20A is a locally secreted protein with low abundance in saliva [<xref ref-type="bibr" rid="B23">23</xref>
] and blood [<xref ref-type="bibr" rid="B24">24</xref>
], suggesting that replacement therapy could provide an option for a treatment or prophylaxis.</p>
