Genes affected

F2R (HGNC:3537): (coagulation factor II thrombin receptor) Coagulation factor II receptor is a 7-transmembrane receptor involved in the regulation of thrombotic response. Proteolytic cleavage leads to the activation of the receptor. F2R is a G-protein coupled receptor family member. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0261 (3974/152126) while in subpopulation NFE AF= 0.039 (2652/67998). AF 95% confidence interval is 0.0378. There are 57 homozygotes in gnomad4. There are 1913 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 3974 AD gene.
