Sequencing-based analysis of the HLA-DPB1 polymorphism in Nu ethnic group of south-west China

Int J Immunogenet. 2006 Dec;33(6):397-400. doi: 10.1111/j.1744-313X.2006.00638.x.

Abstract

In the present study, DNA typing for HLA-DPB1 was performed using polymerase chain reaction-sequencing-based typing method in 72 randomly selected Nu ethnic individuals inhabiting the Yunnan province of south-west China. Among the 12 detected DPB1 alleles, the most frequent was DPB1*1301, with the percentage of 20.83%, followed by DPB1*0501 (19.44%), DPB1*040101 (16.67%) and DPB1*2801 (9.72%). The allele DPB1*1501 was found for the first time in the Chinese population. Neighbour-joining showed that the Nu ethnic minority belonged to East Asian cluster and was most closely related to Lisu, being consistent with the historical records. In addition, the results obtained in this study will also provide useful information on organ transplantation, forensic investigations and disease association studies.
