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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 11 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 10 uncertain in NM_000312.4
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: 1.6095 (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.
PP5
Variant 2-127428371-C-T is Pathogenic according to our data. Variant chr2-127428371-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 536970.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
