Abstract
Seventy-four (50 females and 24 males) consecutively sampled patients with otosclerosis were tissue typed for HLA A and B antigens. There was no significant increase in any A or B antigen, but the frequency of B40 was significantly lower (p<0.05) in patients than in blood donors. No significant difference in HLA antigen frequencies was found between men and women, or in patients with vs. without a family history of otosclerosis.
