RCV001001316 | SCV001158501 | likely pathogenic | Hereditary factor VIII deficiency disease | 2019-06-07 | criteria provided, single submitter | clinical testing | The F8 c.606T>G; p.Ser202Arg variant, also reported as Ser183Arg, has been described in at least one individual with mild hemophilia A (HA; see link to F8 database, Moller-Morlang 1999). It is absent from general population databases (Exome Variant Server and Genome Aggregation Database), indicating it is not a common polymorphism. Another variant at this codon (c.605G>A; p.Ser202Asn) as well as several missense variants at surrounding codons (197, 198, 200, 201, 203) have been described in individuals affected with HA (see link to F8 database and references therein, Arruda 1995, Guillet 2006, Lu 2018). Based on available information, the p.Ser202Arg variant is considered likely pathogenic. REFERENCES Link to F8 database: http://www.factorviii-db.org/ Arruda V et al.
