[HLA antigens and different clinical forms of 21-hydroxylase deficiency in the French population].

HLA associations with 21-OH deficiency were studied on respectively 109 and 60 congenital and late onset French index cases. Significant negative associations were found with antigens B8: congenital forms; B5, DR3: late onset. Significant positive associations were observed with A3, Bw47 (A3 Cw6 Bw47 DR7): congenital forms; B40: salt-wasting form; B5: simple virilizing form; Aw33, B14, DR1, DR2, DRw6 (Aw33 B14 DR1): late onset form. Among late onset patients not bearing B14 antigens significant positive associations were observed with B12 and B35.
