This variant is reported in ClinVar (Variation ID: 10245). It is found in the general population with a low overall allele frequency of 0.001% (2/176848 alleles, including 1 hemizygote) in the Genome Aggregation Database. The arginine at codon 717 is highly conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Based on available information, this variant is considered to be pathogenic. REFERENCES Link to Factor VIII variant database: Diamond C et al.
