Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 7P and 2B.

PM1PM2PM5PP2BP4_Moderate

The NM_000312.4(PROC):c.814C>A(p.Arg272Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,676 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R272C) has been classified as Likely pathogenic.

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 5 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, 8 uncertain in NM_000312.4

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr2-127428374-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 671.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.24638754).
