Evidence submitted by expert panel

Coagulation Factor Deficiency VCEP

The c.1804C>T (p.Arg602Ter) variant is a nonsense variant that is predicted to introduce a premature stop codon in exon 12 and expected to result in nonsense-mediated mRNA decay. This variant is absent from males in gnomAD v2.1.1 and v3.1.1, which meets criteria for PM2_Supporting. More than 25 patients with moderate-severe hemophilia A are reported in the literature and internal laboratory data, meeting criteria for PS4_Very Strong and PP4_Moderate (PMID: 29296726, 18387975, 18691168, 16769589, 8639447, 20331761). 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 F8/F9: PVS1, PS4_Very Strong, PP4_Moderate, PM2_Supporting.

PVS1

The c.1804C>T (p.Arg602Ter) variant is a nonsense variant that is predicted to introduce a premature stop codon in exon 12 and expected to result in nonsense-mediated mRNA decay. Meets PVS1 criteria

PS4

Numerous patients with moderate-severe hemophilia A are reported in the literature and internal laboratory data, meeting criteria for PS4_Very Strong (>8 probands).

PP4_Moderate

Male with severe hemophilia A who had full F8 and F9 gene sequencing and deletion/duplication analysis through MLOF study.

PM2_Supporting

The variant is absent from males in gnomAD v2.1.1 and v3.1.1
