Additionally, a systematic review of reported cases in literature was conducted. The clinical validity of the gene\u2013disease relationship between OSGEP and GAMOS3 was also evaluated in accordance with the ClinGen Gene\u2013Disease Clinical Validity Curation Framework.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The postnatal renal and neurological dysfunction was associated with prenatal manifestations, indicating disease progression. Prominent prenatal features included fetal growth restriction (FGR), microcephaly, oligohydramnios and abnormal cranial imaging. Notably, FGR worsened with advancing gestation, predominantly affecting fetal head and abdominal growth while sparing long bones. Fetal central nervous system magnetic resonance imaging revealed uncommon findings such as abnormal sulcation and increased T2 signal in the white matter, suggestive of myelination defects or leukoencephalopathy. Trio-based medical exome sequencing identified novel variants in the OSGEP gene within this cohort, expanding the known genetic spectrum of GAMOS3. Furthermore, the gene\u2013disease relationship between OSGEP and GAMOS3 was conclusively validated as \u2018Definitive\u2019 according to clinical-genetic criteria.<\/jats:p>\n
