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 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.901

The c.433C>T (p.P145S) alteration is located in exon 3 (coding exon 3) of the ARRDC3 gene. This alteration results from a C to T substitution at nucleotide position 433, causing the proline (P) at amino acid position 145 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
