Abstract excerpt
BACKGROUND: Although bleeding phenotypes and factor (F)VIII activity (FVIII:C) in men with hemophilia A correlate highly with F8 mutations, FVIII:C in female HA carriers is more variable due to mosaicism arising from a second wild-type F8 allele and X-chromosome inactivation (XCI). Conventionally, only female HA carriers with low FVIII:C were considered at risk for bleeding. However, hemostatic FVIII:C levels in...
