| Intellectual disability v9.211 | WSB2 |
Achchuthan Shanmugasundram changed review comment from: PMID:40374945 reported five patients from four unrelated families with developmental delays, brain anomalies, and dysmorphic features with or without intrauterine growth restriction (IUGR) and hypotonia. All five patients had global developmental delay. They were all identified with homozygous predicted loss-of-function (pLoF) or missense variants in WSB2 gene (c.128G>A/ p.Trp43Ter, p.Gln134ArgfsTer14, c.1121G>A/ p.Arg374Gln & c.1187_1188delAA/ p.Lys396ArgfsTer19) inherited from asymptomatic consanguineous parents. There is also functional evidence available from Wsb2-mutant mice, which exhibited several neurological findings that included hyperactivity, altered exploration, and hyper alertness. They also weighed less, had a lower heart rate, and presented an abnormal retinal blood vessel morphology and vasculature pattern along with decreased total thickness of the retina. This gene has not been associated with relevant phenotypes either in OMIM, Gene2Phenotype or ClinGen Sources: Literature; to: PMID:40374945 reported five patients from four unrelated families with developmental delays, brain anomalies, and dysmorphic features with or without intrauterine growth restriction (IUGR) and hypotonia.

| Intellectual disability v9.211 | WSB2 | Achchuthan Shanmugasundram Added comment: Comment on list classification: Although intellectual disability has only been noted in one of four families (family with two patients where ID is moderate in one and severity not given in other), the phenotype is syndromic and GDD is present in all four families. Hence, this gene can be promoted to green rating in the next GMS update. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
