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.

ACMG classification

Verdict is Benign. Variant got -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 id is 2643380.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome 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 gnomad4_exome. There are 2948 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 28 gene
