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.

Ambry Genetics

Jul 20, 2021

The c.70T>C (p.Y24H) alteration is located in exon 1 (coding exon 1) of the ARRDC3 gene. This alteration results from a T to C substitution at nucleotide position 70, causing the tyrosine (Y) at amino acid position 24 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
