The Incidence of HLA Antigens in Leprosy

Abstract
HL-A antigens were studied in 36 patients with leprosy (20 cases were of the lepromatous type and 16 cases were of the tuberculoid type). Eleven of 36 (30.55%) had BW40 as compared to 9.33% of 150 controls. The frequency of BW40 in tuberculoid patients (31.25%) was not different from that in lepromatous cases (30%).
