<front><div type="abstract" xml:lang="en"><p>The Forkhead box G1 (<italic>FOXG1</italic>
) gene has been implicated in severe Rett-like
phenotypes. It encodes the Forkhead box protein G1, a winged-helix transcriptional
repressor critical for forebrain development. Recently, the core <italic>FOXG1</italic>
syndrome
was defined as postnatal microcephaly, severe mental retardation, absent language,
dyskinesia, and dysgenesis of the corpus callosum. We present seven additional patients
with a severe Rett-like neurodevelopment disorder associated with <italic>de novo</italic>
<italic>FOXG1</italic>
point mutations (two cases) or 14q12 deletions (five cases). We expand the
mutational spectrum in patients with <italic>FOXG1</italic>
-related encephalopathies and precise
the core <italic>FOXG1</italic>
syndrome phenotype. Dysgenesis of the corpus callosum and
dyskinesia are not always present in <italic>FOXG1</italic>
-mutated patients. We believe that the
<italic>FOXG1</italic>
gene should be considered in severely mentally retarded patients (no
speech-language) with severe acquired microcephaly (−4 to−6 SD) and few
clinical features suggestive of Rett syndrome. Interestingly enough, three 14q12 deletions
that do not include the <italic>FOXG1</italic>
gene are associated with phenotypes very
reminiscent to that of <italic>FOXG1</italic>
-mutation-positive patients. We physically mapped a
putative long-range <italic>FOXG1</italic>
-regulatory element in a 0.43 Mb DNA segment
encompassing the <italic>PRKD1</italic>
locus. In fibroblast cells, a <italic>cis</italic>
-acting
regulatory sequence located more than 0.6 Mb away from <italic>FOXG1</italic>
acts as a
silencer at the transcriptional level. These data are important for clinicians and for
molecular biologists involved in the management of patients with severe encephalopathies
compatible with a <italic>FOXG1</italic>
-related phenotype.</p>

<abstract><p>The Forkhead box G1 (<italic>FOXG1</italic>
) gene has been implicated in severe Rett-like
phenotypes. It encodes the Forkhead box protein G1, a winged-helix transcriptional
repressor critical for forebrain development. Recently, the core <italic>FOXG1</italic>
syndrome
was defined as postnatal microcephaly, severe mental retardation, absent language,
dyskinesia, and dysgenesis of the corpus callosum. We present seven additional patients
with a severe Rett-like neurodevelopment disorder associated with <italic>de novo</italic>
<italic>FOXG1</italic>
point mutations (two cases) or 14q12 deletions (five cases). We expand the
mutational spectrum in patients with <italic>FOXG1</italic>
-related encephalopathies and precise
the core <italic>FOXG1</italic>
syndrome phenotype. Dysgenesis of the corpus callosum and
dyskinesia are not always present in <italic>FOXG1</italic>
-mutated patients. We believe that the
<italic>FOXG1</italic>
gene should be considered in severely mentally retarded patients (no
speech-language) with severe acquired microcephaly (−4 to−6 SD) and few
clinical features suggestive of Rett syndrome. Interestingly enough, three 14q12 deletions
that do not include the <italic>FOXG1</italic>
gene are associated with phenotypes very
reminiscent to that of <italic>FOXG1</italic>
-mutation-positive patients. We physically mapped a
putative long-range <italic>FOXG1</italic>
-regulatory element in a 0.43 Mb DNA segment
encompassing the <italic>PRKD1</italic>
locus. In fibroblast cells, a <italic>cis</italic>
-acting
regulatory sequence located more than 0.6 Mb away from <italic>FOXG1</italic>
acts as a
silencer at the transcriptional level. These data are important for clinicians and for
molecular biologists involved in the management of patients with severe encephalopathies
compatible with a <italic>FOXG1</italic>
-related phenotype.</p>
