Factor 8 intron 22 inversion
Webcommon deficiency of factor VIII is either inversion of intron 22 (Inv 22, ~ 40-50%) or inversion of intron 1 (Inv 1, ~ 2-5%) which occur in severe cases of HA (Lakich et WebIntron-22 (Inv22) and intron-1 (Inv1) inversions account for approximately one half of all severe cases of hemophilia A (SHA) worldwide. Inhibitor development against exogenous factor VIII (FVIII) represents a major complication in HA. The causative F8 mutation is considered the most decisive factor conditioning inhibitor development.
