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):

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 56 curated pathogenic missense variants (we use a threshold of 10). The gene has 16 curated benign missense variants. Gene score misZ: 0.88339 (below the threshold of 3.09). Trascript score misZ: 1.2829 (below the threshold of 3.09). GenCC associations: The gene is linked to thrombophilia due to protein C deficiency, autosomal dominant, thrombophilia due to protein C deficiency, autosomal recessive, hereditary thrombophilia due to congenital protein C deficiency.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.64).

BP6

Variant 2-127419981-C-T is Benign according to our data. Variant chr2-127419981-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 1088403.Status of the report is criteria_provided_single_submitter, 1 stars.
