Added comment: 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. 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.

Intrauterine growth restriction (IUGR) was reported in two unrelated patients and Oligohydramnios was reported in a different unrelated patient.

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.
