title: HLA association of anti-IgA antibody production.
abstract: We have HLA typed 46 unrelated IgA deficient blood donors in our region. A weak association to DR3 (RR = 2.07) was observed. However, owing to the heterogeneous nature of this group, we found DR7 may be associated with those who developed class-specific anti-IgA antibodies (RR = 2.94), whereas DR1 may be associated with those who did not (RR = 2.42).
