The genes for 5-lipoxygenase activating protein (ALOX5AP) and phosphodiesterase 4D (PDE4D) have been demonstrated as susceptibility genes for lacunar in the Icelandic and Pakistani populations,but little is known about the role of these genes in Chinese populations.The present study utilized polymerase chain reaction and ligase detection reaction to detect single nucleotide polymorphisms (SNPs) in 280 consecutive stroke patients and 258 unrelated population-based controls from Nanjing,Jiangsu Province,China.The allele frequency,genotypes,and haplotypes of the two SNPs (rs456009 and rs966221) in PDE4D were similar between the two groups.However,A allele frequency of rs4073259 (A/G) and rs4769055 (A/C) in the ALOX5AP gene exhibited differences in two groups,and especially the haplotype of the SNP was significantly different between the two groups.Results suggested that the ALOX5AP gene might be involved in lacunar infarct,while PDE4D gene was not a risk factor for lacunar infarct in individuals from Jiangsu Province,China.
The genes for 5-lipoxygenase activating protein (ALOX5AP) and phosphodiesterase 4D (PDE4D) have been designed to remove as genes for lacunar in the Icelandic and Pakistani populations, but little known to the role of these genes in Chinese populations.The present study utilized polymerase chain reaction and ligase detection reaction to detect single nucleotide polymorphisms (SNPs) in 280 consecutive stroke patients and 258 unrelated population-based controls from Nanjing, Jiangsu Province, China. The allele frequency, genotypes, and haplotypes of the two SNPs (rs456009 and Of A allele frequency of rs4073259 (A / G) and rs4769055 (A / C) in the ALOX5AP gene characterized differences in two groups, and particularly the haplotype of the SNP was significantly different results of the ALOX5AP gene might be involved in lacunar infarct, while PDE4D gene was not a risk factor for lacunar infarct in indi viduals from Jiangsu Province, China.
