Genes affected

PROC (HGNC:9451): (protein C, inactivator of coagulation factors Va and VIIIa) This gene encodes a vitamin K-dependent plasma glycoprotein. The encoded protein is cleaved to its activated form by the thrombin-thrombomodulin complex. This activated form contains a serine protease domain and functions in degradation of the activated forms of coagulation factors V and VIII. Mutations in this gene have been associated with thrombophilia due to protein C deficiency, neonatal purpura fulminans, and recurrent venous thrombosis.[provided by RefSeq, Dec 2009]

PROC Gene-Disease associations (from GenCC):

• thrombophilia due to protein C deficiency, autosomal dominant

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.634 is higher than 0.05.
