Genes affected

ARRDC3 (HGNC:29263): (arrestin domain containing 3) This gene encodes a member of the arrestin family of proteins, which regulate G protein-mediated signaling. The encoded protein is thought to act as a regulator of breast cancer growth and progression by binding to a phosphorylated form of integrin beta4, a tumor-related antigen, targeting the integrin for internalization and degradation.

The c.325A>G (p.R109G) alteration is located in exon 2 (coding exon 2) of the ARRDC3 gene. This alteration results from a A to G substitution at nucleotide position 325, causing the arginine (R) at amino acid position 109 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
