title: [HLA-DM polymorphisms in Guizhou Han individuals].
abstract: Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine genetic polymorphisms at HLA-DMA/DMB loci in 125 healthy unrelated Han individuals from Guizhou Province. We found that the frequencies of DMA*0101, DMA*0102, and DMA*0103 alleles were 0.720, 0.242, and 0.036, respectively. The frequencies of DMB*0101, DMB*0102, DMB*0103, and DMB*0104 alleles were 0.620, 0.156, 0.188, and 0.036, respectively. Common genotypes for DMA were DMA*0101/0101 and 0101/0102. Common genotypes for DMB were DMB*0101/0101, 0101/0102, and 0101/0103. These results showed that the genetic polymorphism of HLA-DM gene in Han individuals from Guizhou Province is distinct from other regions.
