title: HLA class I and II polymorphisms in the Gujjar population from Pakistan.
abstract: HLA polymorphisms at the HLA -A, -B, -C, -DRB and -DQB1 loci were investigated in the Gujjar population from the Punjab province of Pakistan. The Gujjars (n = 97) were genotyped using sequence specific primers for polymerase chain reaction. The allele and haplotype frequencies were calculated and a neighbor-joining (NJ) tree comparing the Gujjar with other populations was constructed. The class I allelic groups with a frequency greater than 10% include A*01, A*02, A*11, A*26 and A*31 at the HLA-A locus, B*08 and B*51 at the HLA-B locus and C*07 and C*14 at the HLA-C locus. Among the 12 allelic groups detected at the DRB1* locus, *03, *13, and *15 were present at frequencies higher than 10% whereas at the DQB1 locus, the allelic groups*06 and *02 accounted for over half of the Gujjar population. HLA-A*31-B*51-DRB1*13 was the most common (8.8%) haplotype in this population. A NJ tree revealed that the Pakistani Gujjar are closely related to the Golla tribe from Andhra Pradesh in India. The two populations are dedicated to the same profession, cattle breeding. HLA analyses of additional Punjab castes would provide valuable information for anthropological, organ transplantation and genetic disease studies.
