ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001802300 SCV002050166 likely pathogenic Hereditary factor VIII deficiency disease 2021-11-12 criteria provided, single submitter clinical testing The F8 c.665A>C; p.Asp222Ala variant (rs137852396), also known as Asp203Ala, is reported in the literature in individuals affected with hemophilia A (see link to FVIII database, Johnsen 2017). This variant is absent from the Genome Aggregation Database, indicating it is not a common polymorphism. The aspartate at codon 222 is highly conserved, and computational analyses predict that this variant is deleterious (REVEL: 0.883). Additionally, other variants at this codon (c.665A>T; p.Asp222Val, c.665A>G; p.Asp222Gly) have been reported in individuals with hemophilia A (see link to FVIII database and references therein, Bogdanova 2007, Johnsen 2017). Based on available information, this variant is considered to be likely pathogenic. References: Link to FVIII database: https://f8-db.eahad.org/index.php Bogdanova N et al.
