Fifty unrelated Indian Gurkha of Nepalese origin were studied to analy
se the HLA antigen profile and their relation with other populations.
Halotype B35-Cw4 occurred with highest incidence and significant posit
ive linkage disequilibrium in Gurkhas. Haplotype A10-B8 which occurs w
ith the highest frequency in north Indians was also observed to occur
with significant positive linkage in Gurkhas, HLA profile of Gurkhas t
hus may be the result of long-term isolation and genetic drift.
