Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001193621.3(PINLYP):​c.26C>G​(p.Thr9Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000506 in 1,383,826 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 11/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T9I) has been classified as Uncertain significance.

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]

ENSG00000268361 (HGNC:):

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]

XRCC1 Gene-Disease associations (from GenCC):

• head and neck cancer

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics
• spinocerebellar ataxia, autosomal recessive 26

  Inheritance: Unknown Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.08076012).
