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]

Phosphorus, Inc.

Jan 14, 2022

This missense variant results in an amino acid substitution of valine with methionine at codon 11 of the PROC gene (NM_000312.3). The variant has no entry in ClinVar and has occurred in GnomAD with a total MAF of 0.0032% and highest MAF of 0.0065% in the African population. This position is not conserved. In silico functional algorithms agreed, with PolyPhen calling it benign, and SIFT tolerated, but no functional studies were performed to confirm these predictions. The variant has not occurred in literature associated with disease. Considering that this is a rare variant, whose impact on the protein and association with disease are unknown, it has been classified as a Variant of Uncertain Significance. -
