摘要: 目的 探寻甘油-3-磷酸脱氢酶样基因(glycerol-3-phosphate dehydrogenase 1 like gene,GPD1-L)的变异位点,讨论其与青壮年猝死综合征(sudden manhood death syndrome,SMDS)的关系。 方法 提取SMDS组及健康对照组血样的基因组DNA,采用PCR法扩增GPD1-L基因编码区外显子、外显子-内含子交界区以及3′侧翼区序列,直接进行DNA测序以明确遗传变异类型,并进行基因型频率和等位基因频率的统计学分析。 结果 在SMDS组中共检测到2个变异位点,c.465C>T和c.*18G>T,后者在SMDS组和对照组中基因型分布和等位基因频率存在一定差异,但无统计学意义(P>0.05)。 结论 GPD1-L基因变异与中国人SMDS发生的相关性尚有待进一步研究。

Abstract: Objective To analyze the variations of glycerol-3-phosphate dehydrogenase 1 like gene (GPD1-L) and address the association with sudden manhood death syndrome (SMDS). Methods The genomic DNA was extracted from blood samples of the SMDS group and the normal control group. The exons, exon-intron boundaries and 3′-UTRs of coding region of GPD1-L were PCR amplified and DNA sequenced directly to confirm the types of variations. The genotype frequency and allele frequency were analyzed statistically. Results There were two variants in the SMDS group, c.465C>T and c.*18G>T, the latter existed certain degree difference of genotype distribution and allele frequency between the SMDS group and the control group, but there was no statistically significant(P>0.05). Conclusion The relation between gene mutation of GPD1-L and the occurrence of Chinese SMDS deserves a further research.
