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]

The c.835G>C (p.D279H) alteration is located in exon 6 (coding exon 6) of the UBASH3B gene. This alteration results from a G to C substitution at nucleotide position 835, causing the aspartic acid (D) at amino acid position 279 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
