• Conservation: PhyloP100: 6.27

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.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3280178).

The c.1147A>G (p.I383V) alteration is located in exon 7 (coding exon 7) of the ARRDC3 gene. This alteration results from a A to G substitution at nucleotide position 1147, causing the isoleucine (I) at amino acid position 383 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
