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.

WSB2 Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0037802756).
• BP6: Variant 12-118043202-C-T is Benign according to our data. Variant chr12-118043202-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 2643380.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00396 (5792/1461894) while in subpopulation MID AF = 0.0182 (105/5768). AF 95% confidence interval is 0.0154. There are 28 homozygotes in GnomAdExome4. There are 2948 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 28 AR gene
