摘  要:

目的我国汉族人群FcαR1基因5'-UTR区3个SNPs多态性颁的特征及将其与日本人群进行比较。方法提取368例正常广东汉族人基因组,DNA扩增FcαR1基因5'-UTR相关区域并直接测序鉴定基因型。结果①我国汉族人群FcαR1基因5'-UTR区3个SNPs多态性:-114位点TT基因型最常见(52.7%),CC基因型分布最少(7.3%),-27位点TT(85.1),CC(1.4%),+56位点TC基因型 最常见(51.4%),CC基因型分布最少(12.0%);②等住基因分布频率:-114位点T(72.7%)、C(27.3%):+56位点T(62.4%)、C(37.6%)及-27位点T(91.8%)、C(8、2%);③主要单倍型:TTT(61.9%)、CTC(27.2%)和TCC(7.9%)。结论与日本人群比较,我国汉族人群FcαR1基因5'-UTR区-114T/C及+56T/C无论是基因型,还是等位基因频率分布,差异均无显著性。[著者文摘]

Abstract:

Objective To investigate the distribution of SNPs in FcαR1 gene 5'-UTR and promoter region and to compare them with the Japanese. Methods Genomic DNA was extracted from 368 healthy Chinese Han subjects, genotypes of the SNPs in FcαR1 gene 5' - UTR and promoter region were determined by PCR and direct sequencing. Comparing between two groups was conducted with chi square test. Results 1. the genotypes' frequencies of the 3 SNPs in FcαR1 gene 5' - UTR and promoter region were Tr (52.7%) ,CC (7.3%) in - 114 locus,TT(85.1% ) ,CC( 1.4% ) in - 27 locus, TC (51.4%) ,CC ( 12.0% ) in +56 locus. 2. the alleles' frequencies of the 3 SNPs in FcαR1 gene 5' - UTR region were T( 72.7% ) , C (27.3%) in - 114 locus; T(62.4% ), C (37.6%) in + 56 locus and T (91.8%), C(8.2% ) in -27 locus. 3. Main haplotype pattern is TIT (61.9%), CTC(27.2% ) and TCC (7, 9% )s. Conclusion There was no significant difference in the distribution of SNPs in FcαR1 gene 5' - UTR and promoter region in Chinese Han compared with the Japanese.[著者文摘]
