ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV000757251 SCV000885401 pathogenic not provided 2018-02-02 criteria provided, single submitter clinical testing The F8 c.4328_4331delAAGA; p.Lys1443fs variant (rs387906454), also known as codon 1422 4bp del and codon 1423 4 bp del, is described in the medical literature in individuals with severe hemophilia (Habart 2003, Naylor 1993, Waseem 1999). The variant is described in the ClinVar database (Variation ID: 10259). The variant is not listed in the Genome Aggregation Database, indicating it is not a common polymorphism. This variant deletes four nucleotides, causes a frameshift, and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Considering available information, this variant is considered pathogenic for severe hemophilia. References: Habart D et al.
