Abstract
To study the distribution of KIR3DL2 alleles among ethnic Han Chinese from Zhejiang. Genomic DNA was extracted by using a magnetic bead method. The full sequence of the KIR3DL2 gene was amplified with four pairs by PCR primers. The coding regions of 208 unrelated ethnic Han Chinese blood donors were analyzed using a BigDye Terminator v3.1 Sequencing Kit. The genotypes were assigned based on the nucleotide polymorphism of the KIR3DL2 gene. Among the 208 samples, 133 were KIR3DL2 heterozygotes and 75 were homozygotes. Forty six KIR3DL2 genotypes were detected. Respectively, 70, 33 and 23 individuals were found to have a KIR3DL2*00201/KIR3DL2*00201, KIR3DL2*00201/KIR3DL2*00701, and KIR3DL2*00201/KIR3DL2*01001 genotype. Twenty-two KIR3DL2 alleles were discovered, and the frequencies of KIR3DL2*00201, KIR3DL2*00701 and KIR3DL2*01001 were 57.45%, 13.46% and 9.13%, respectively. The distribution of KIR3DL2 alleles among ethnic Han Chinese in Zhejiang has been determined and fits the criteria for genetic polymorphism.
