ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001001039 SCV001158153 pathogenic Hereditary factor VIII deficiency disease 2019-01-24 criteria provided, single submitter clinical testing The F8 c.6638C>T; p.Ser2213Phe variant, also reported as Ser2194Phe, has been described in at least one individual affected with severe hemophilia A (Guillet 2006). It is absent from general population databases (Exome Variant Server and Genome Aggregation Database), indicating it is not a common polymorphism. The serine at codon 2213 is highly conserved, and computational algorithms (PolyPhen-2, SIFT) predict that this variant is deleterious. Additionally, other variants at this codon (c.6638C>G; p.Ser2213Cys, c.6637T>C; p.Ser2213Pro, and c.6638C>A; p.Ser2213Tyr) have been reported in individuals with severe hemophilia A and are considered pathogenic (see link to F8 database and references therein, Santacroce 2008). Based on available information, the p.Ser2213Phe variant is considered pathogenic. REFERENCES Link to F8 database: http://www.factorviii-db.org/ Guillet B et al.
