ClinGen Coagulation Factor Deficiency Variant Curation Expert Panel, Clingen RCV004577530 SCV005061651 pathogenic Hereditary factor IX deficiency disease 2024-04-26 reviewed by expert panel curation The c.1009G>A (NM_000133.4) variant in F9 is a missense variant predicted to cause substitution of alanine by threonine at amino acid 337 (p.Ala337Thr). This variant is absent from males in population databases (gnomAD v2.1.1/gnomAD v3). This variant has been reported in at least 8 unique probands with mild to severe hemophilia B (PMID: 8091381; PMID: 11013449; PMID: 2726481), meeting phenotypic criteria for F9. The computational predictor REVEL gives a score of 0.783, which is above the threshold of 0.6, evidence that correlates with impact to F9 function (PP3). In summary, this variant meets criteria to be classified as pathogenic. ACMG/AMP criteria applied, as specified by the Coagulation Factor Deficiency Variant Curation Expert Panel for F9: PS4_Very Strong + PM2_Supporting + PP3.
