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.1037C>T (p.P346L) alteration is located in exon 7 (coding exon 7) of the ARRDC3 gene. This alteration results from a C to T substitution at nucleotide position 1037, causing the proline (P) at amino acid position 346 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
