Genes affected

P2RY12 (HGNC:18124): (purinergic receptor P2Y12) The product of this gene belongs to the family of G-protein coupled receptors. This family has several receptor subtypes with different pharmacological selectivity, which overlaps in some cases, for various adenosine and uridine nucleotides. This receptor is involved in platelet aggregation, and is a potential target for the treatment of thromboembolisms and other clotting disorders. Mutations in this gene are implicated in bleeding disorder, platelet type 8 (BDPLT8). Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]

P2RY12 links:

MED12L (HGNC:16050): (mediator complex subunit 12L) The protein encoded by this gene is part of the Mediator complex, which is involved in transcriptional coactivation of nearly all RNA polymerase II-dependent genes. The Mediator complex links gene-specific transcriptional activators with the basal transcription machinery. [provided by RefSeq, May 2010]

The c.836T>C (p.V279A) alteration is located in exon 3 (coding exon 1) of the P2RY12 gene. This alteration results from a T to C substitution at nucleotide position 836, causing the valine (V) at amino acid position 279 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 279 of the P2RY12 protein (p.Val279Ala). This variant is present in population databases (rs761528306, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with P2RY12-related conditions. ClinVar contains an entry for this variant (Variation ID: 2138834). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
