ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001802450 SCV002048519 likely pathogenic Hereditary factor VIII deficiency disease 2021-06-03 criteria provided, single submitter clinical testing The F8 c.6118T>G; p.Cys2040Gly variant, also known as p.Cys2021Gly, is reported in the literature in multiple individuals affected with mild to moderate hemophilia A (see F8 database and references therein, Eckhardt 2013). This variant is absent from the Genome Aggregation Database, indicating it is not a common polymorphism. Additionally, another variant at this codon (c.6119G>A, p.Cys2040Tyr) has been reported in individuals with mild to moderate hemophilia A and is considered disease causing (F8 database, Green 2008). The cystine at codon 2040 is highly conserved, and computational analyses predict that this variant is deleterious (REVEL: 0.772). Based on available information, this variant is considered to be likely pathogenic. References: Factor VIII variant database: https://f8-db.eahad.org/index.php Eckhardt CL et al.
