In Shandong Hart donors, 20 alleles at HLA-A locus and 46 alleles at HLA-B locus could be detected as revealed in the present study. Among the 20 alleles at HLA-A locus, the most prevalent five alleles included A * 02(0.3041), A * 11(0. 1443), A * 24(0. 1434), A * 30(0.0975) and A 33(0.0859), while, the alleles with lower gene frequencies included A * 34(0.0006), A * 25 (0.0005), A * 66(0.0005), A * 74(0.0004) and A * (0.0001). Of the 46 HLA-B alleles detected, the most prevalent five alleles were B * 13(0.1348), B * 51(0.0713), B * 62(0.0712), B * 61 (0.0676) and B * 60(0.0642); while alleles with lower gene frequencies included B * 77(0.0001), B * 76(0.0002), B * 47(0.0003), B * 42(0.0003) and B * 72(0.0004). In comparison with those of the other Han population in China, the HLA-A, -B gene frequencies in the umbilical cord blood of Shandong province possess unique distribution features among the investigated populations from various regions of the same race origin, and the differences in various regions of the same race were less than those among the different race. It is evident that the HLA-A,-B alleles of the umbilical cord blood taken in Shangdong province show high degree of polymorphism, and it might be part of those of Northem Han population in China. So, it is reasonable for patients of Northern Chinese to receive HLA class Ⅰ -match transplant of cord blood stem ceils for tissue and organ transplantation from Shangdong umbilical cord blood bank.展开更多
