Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PP2PP3_ModeratePP5

The NM_000312.4(PROC):c.1335C>G(p.Ile445Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000744 in 1,613,868 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I445L) has been classified as Uncertain significance.

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: Uncertain_significance. The variant received 4 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: 1.6095 (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.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.926

PP5

Variant 2-127428895-C-G is Pathogenic according to our data. Variant chr2-127428895-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 676.Status of the report is no_assertion_criteria_provided, 0 stars.
