摘要: 目的 寻求窖蛋白(caveolin,CAV)基因变异位点,探讨其与不明原因猝死(sudden unexplained death,SUD)的相关性。 方法 收集SUD组(71例)、冠状动脉疾病(coronary artery disease,CAD)组(62例)和对照组(60例)血样,分别提取基因组DNA,采用PCR方法扩增CAV1与CAV3基因编码区及外显子-内含子拼接区,进行直接测序,以明确CAV基因的遗传变异类型,并进行统计学分析。 结果 在SUD组中共检测到4个可能有意义的变异位点,其中2个为新发现的突变位点,分别为CAV1:c.45C>T(T15T)和CAV1:c.512G>A(R171H);2个为SNP位点,分别为CAV1:c.246C>T(rs35242077)和CAV3:c.99C>T(rs1008642),且这两个SNP位点的基因型频率和等位基因频率在SUD组与对照组中差异具有统计学意义(P<0.05),在CAD组中均未发现上述变异位点。 结论 部分SUD可能与CAV1和CAV3基因变异存在一定相关性。

Abstract: Objective To explore the genetic variation sites of caveolin (CAV) and their correlation with sudden unexplained death (SUD). Methods The blood samples were collected from SUD group (71 cases), coronary artery disease (CAD) group (62 cases) and control group (60 cases), respectively. The genome DNA were extracted and sequencing was performed directly by amplifying gene coding region and exon-intron splicing region of CAV1 and CAV3 using PCR. The type of heritable variation of CVA was confirmed and statistical analysis was performed. Results A total of 4 variation sites that maybe significative were identified in SUD group, and two were newfound which were CAV1: c.45C>T (T15T) and CAV1:c.512G>A (R171H), and two were SNP loci which were CAV1:c.246C>T (rs35242077) and CAV3:c.99C>T (rs1008642) and had significant difference (P<0.05) in allele and genotype frequencies between SUD and control groups. Forementioned variation sites were not found in CAD group. Conclusion The variants of CAV1 and CAV3 may be correlated with a part of SUD group.
