It is observed in the general population at a low overall frequency of 0.0017% (3/181547 alleles, 1 hemizygote) in the Genome Aggregation Database, indicating it is not a common polymorphism. The arginine at residue 717 is highly conserved, and other missense variants at this position (p.Arg717Trp, p.Arg717Leu, and p.Arg717Pro) have also been reported in individuals with hemophilia A (see link to F8 database and references therein, Markoff 2009). Based on the available information, the p.Arg717Gln variant is considered pathogenic. REFERENCES Factor VIII variant database: David D et al.
