RCV001002229 | SCV001160104 | likely pathogenic | Hereditary factor VIII deficiency disease | 2018-11-20 | criteria provided, single submitter | clinical testing | The F8 c.382T>C; p.Ser128Pro variant, also known as p.Ser109Pro, is reported in the literature in one individual affected with severe hemophilia A (Gorziza 2013). This variant is absent from general population databases (1000 Genomes Project, Exome Variant Server, and Genome Aggregation Database), indicating it is not a common polymorphism. The serine at codon 128 is highly conserved and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Additionally, other variants in adjacent codons (c.385G>A; p.Glu129Lys and c.386A>T; p.Glu129Val) have been reported in individuals with severe hemophilia A (Maugard 1998, Reitter 2010). Based on available information, the p.Ser128Pro variant is considered to be likely pathogenic. REFERENCES Gorziza et al.
