RESUMO
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.
