ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001802542 SCV002048817 likely pathogenic Hereditary factor VIII deficiency disease 2020-10-12 criteria provided, single submitter clinical testing The F8 c.55A>C; p.Ser19Arg variant, to our knowledge, is not reported in the literature. However, other DNA changes leading to the same protein change (c.57T>A; p.Ser19Arg and c.57T>G; p.Ser19Arg) have been described in individuals with hemophilia and are considered pathogenic (Lu 2018, Strmecki 1999). The c.55A>C; p.Ser19Arg variant is also absent from general population databases (Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. The serine at codon 19 is moderately conserved, and computational analyses predict that this variant is deleterious (REVEL: 0.735). Based on available information, this variant is considered to be likely pathogenic. References: Lu Y et al. Spectrum and origin of mutations in sporadic cases of haemophilia A in China.
