Genes affected

UBASH3B (HGNC:29884): (ubiquitin associated and SH3 domain containing B) This gene encodes a protein that contains a ubiquitin associated domain at the N-terminus, an SH3 domain, and a C-terminal domain with similarities to the catalytic motif of phosphoglycerate mutase. The encoded protein was found to inhibit endocytosis of epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor. [provided by RefSeq, Jul 2008]

(HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09207845).

The c.581C>T (p.A194V) alteration is located in exon 4 (coding exon 4) of the UBASH3B gene. This alteration results from a C to T substitution at nucleotide position 581, causing the alanine (A) at amino acid position 194 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
