ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV003736380 SCV004563194 pathogenic not provided 2023-07-07 criteria provided, single submitter clinical testing The F8 c.4473C>G; p.Tyr1491Ter variant, also known as Y1492X, as well as another nonsense variant at the same position (c.4473C>A; p.Tyr1491Ter, ClinVar Variation ID: 449368), are reported in the literature in multiple individuals affected with severe hemophilia A (Casana 2008, Green 2008, Johnsen 2017). The c.4473C>G; p.Tyr1491Ter variant is absent from the Genome Aggregation Database, indicating it is not a common polymorphism. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be pathogenic. References: Casana P et al. Severe and moderate hemophilia A: identification of 38 new genetic alterations.
