Genes affected

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]

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]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• PP2: Missense variant where missense usually causes diseases, MED12L
• BP4: Computational evidence support a benign effect (MetaRNN=0.0025772154).
• BP6: Variant 3-151372636-G-A is Benign according to our data. Variant chr3-151372636-G-A is described in ClinVar as [Benign]. Clinvar id is 1321166.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.372 is higher than 0.05.
