Genes affected
WSB2 (HGNC:19222): (WD repeat and SOCS box containing 2) This gene encodes a member of the WD-protein subfamily. The encoded protein contains five WD-repeats spanning most of the protein and an SOCS box in the C-terminus. The SOCS box may act as a bridge between specific substrate-binding domains and E3 ubiquitin protein ligases. Three transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2021The c.659C>T (p.S220L) alteration is located in exon 5 (coding exon 5) of the WSB2 gene. This alteration results from a C to T substitution at nucleotide position 659, causing the serine (S) at amino acid position 220 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
