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.

The c.785A>G (p.N262S) alteration is located in exon 6 (coding exon 6) of the WSB2 gene. This alteration results from a A to G substitution at nucleotide position 785, causing the asparagine (N) at amino acid position 262 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
