【摘要】 目的分析中国暗娼人群中DC-SIGN及DC-SIGNR基因多态性的分布,比较不同研究人群等位基因频率分布。方法PCR检测234例HIV阴性暗娼DC-SIGN及DC-SIGNR基因多态性。结果DC-SIGN基因型在234例中发现4例突变杂合子。DC-SIGNR等位基因频率以7次重复最为常见(65．2％),其次为5次重复(18．4％)和9次重复(1 1．9％),其基因频率分布与国外报道差异有统计学意义。结论DC-SIGN基因具有多态性,而DC-SIGNR基因多态性分布同国外报道比较存在差异。更多还原

【Abstract】 Objective To determine the genetic polymorphisms of DC-SIGN and DC-SIGNR among HIV negative Chinese female sex workers. Methods The 69 bp tandem repeat numbers in exon 4 of the DC-SIGN and DC-SIGNR were examined by PCR in 234 HIV-1-seronegative female commercial sex workers. Results It was found that 4 of 234 individuals were heterozygous in DC-SIGN. For DC-SIGNR, the allele frequencies were seven times repeated in 65.2%, 5 in 18.4%, and 9 in 11.9%. Those patterns of alleles frequencies were significantly different compared with those reported in the Caucasians residing in Europe. Conclusion Polymorphisms of DC-SIGN repeat region seem to be infrequent in Chinese female sex workers and those of DC-SIGNR are different from what reported in other races.更多还原
