  1. Prevalence of antithrombin deficiency in the healthy population.

    Article - En anglais

    In a cohort of 9669 blood donors we have identified 16 cases of congenital AT deficiency (1 in 600) by way of family studies and AT gene analysis.

    Two donors had type I AT deficiency (prevalence 0.21 per 1000 ; 95% CI=0.03/1000 to 0.75/1000), their families displaying a symptomatic phenotype. 14 donors had a type II deficiency (prevalence 1.45 per 1000 ; 95% CI=0.79/1000 to 2.43/1000) : one recurring and three unique mutations.

    None of these type II deficiencies appeared to confer a high thrombotic risk despite many of the affected individuals having experienced potentially prothrombotic challenges.

    The high frequency of these relatively asymptomatic variants may reflect a selection bias in the study population.
