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]

Thrombophilia due to protein C deficiency, autosomal dominant

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 31, 2021	This sequence change replaces glycine with serine at codon 18 of the PROC protein (p.Gly18Ser). The glycine residue is weakly conserved and there is a small physicochemical difference between glycine and serine. This variant is present in population databases (rs146793243, ExAC 0.03%). This missense change has been observed in individual(s) with protein C deficiency (PMID: 22627591). This variant is also known as Gly25Ser. ClinVar contains an entry for this variant (Variation ID: 161337). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -
Uncertain significance, criteria provided, single submitter	research	CSER _CC_NCGL, University of Washington	Jun 01, 2014	Low GERP score may suggest that this variant may belong in a lower pathogenicity class -
