[Polymorphism of human killer cell immunoglobulin-like receptor gene in Chinese Jiangsu Han population].
This study was purposed to investigate the distribution of killer cell immunoglobulin-like receptor(KIR)in Jiangsu Han population of China. KIR genomic typing were analyzed by PCR-SSP typing methods in 269 randomly unrelated healthy individuals. The results showed that all 16 known KIR genes were found in Jiangsu Han population, the total KIR genes found in Jiangsu Han population were 34 genes. Out of 34 KIR found genotypes, 15 genotypes (AA1, BX2, BX3, BX4, BX5, BX6, BX8, BX9, BX11, BX13, BX33, BX68, BX69, BX70, BX75) had also been identified in Zhejiang and Hong Kong populations, otherwise, 19 genotypes (BX10, BX12, BX17, BX23, BX26, BX27, BX28, BX31, BX35, BX42, BX47, BX57, BX72, BX74, BX79, BX154, BX188, BX231, BX370) had never been observed in Zhejiang and Hong Kong populations. The rare allele BX42 (detected only in Greece population) and BX231 (detected only in Sweden population) and BX370 (detected only in Macedonia population) were identified in Jiangsu Han population. In conclusion, all 16 known KIR genes were detected in Jiangsu Han population, the total 34 KIR genotypes are found in Jiangsu province, among them the BX42, BX231 and BX370 are rare KIR genotypes.
