Genes affected

PROS1 (HGNC:9456): (protein S) This gene encodes a vitamin K-dependent plasma protein that functions as a cofactor for the anticoagulant protease, activated protein C (APC) to inhibit blood coagulation. It is found in plasma in both a free, functionally active form and also in an inactive form complexed with C4b-binding protein. Mutations in this gene result in autosomal dominant hereditary thrombophilia. An inactive pseudogene of this locus is located at an adjacent region on chromosome 3. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar processing to generate mature protein. [provided by RefSeq, Oct 2015]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_000313.4

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 34 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.58456 (below the threshold of 3.09). Trascript score misZ: 1.9528 (below the threshold of 3.09). GenCC associations: The gene is linked to thrombophilia due to protein S deficiency, autosomal dominant, hereditary thrombophilia due to congenital protein S deficiency, thrombophilia due to protein S deficiency, autosomal recessive, protein S deficiency.

PP5

Variant 3-93910681-C-T is Pathogenic according to our data. Variant chr3-93910681-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 161354.
