Genes affected

PINLYP (HGNC:44206): (phospholipase A2 inhibitor and LY6/PLAUR domain containing) Predicted to enable phospholipase inhibitor activity. Predicted to be involved in negative regulation of catalytic activity. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

XRCC1 (HGNC:12828): (X-ray repair cross complementing 1) The protein encoded by this gene is involved in the efficient repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents. This protein interacts with DNA ligase III, polymerase beta and poly (ADP-ribose) polymerase to participate in the base excision repair pathway. It may play a role in DNA processing during meiogenesis and recombination in germ cells. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.08506212).

The c.183C>G (p.S61R) alteration is located in exon 3 (coding exon 2) of the PINLYP gene. This alteration results from a C to G substitution at nucleotide position 183, causing the serine (S) at amino acid position 61 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
