ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001802699 SCV002049741 likely pathogenic Hereditary factor VIII deficiency disease 2021-03-11 criteria provided, single submitter clinical testing The F8 c.1430G>T; p.Gly477Val variant, also known as G458V, is reported in the literature in multiple individuals affected with mild to moderate hemophilia A (Castaman 2009, Frusconi 2002, Markoff 2009, see link to F8 database). This variant is absent from the Genome Aggregation Database, indicating it is not a common polymorphism. The glycine at codon 477 is highly conserved, and computational analyses predict that this variant is deleterious (REVEL: 0.919). Based on available information, this variant is considered to be likely pathogenic. References: Link to F8 database: https://f8-db.eahad.org/ Castaman G et al.
