Objective To study the distribution characteristics of single nucleotide polymorphisms (SNP) of miR-107 gene rs2296616 C/T in Guangxi healthy population and comparison with that in different ethnic populations, and further to explore the correlation between rs2296616 C/T SNP and blood lipid level. Methods The polymorphisms of miR-107 gene rs2296616 C/T among 372 Chinese healthy individuals of Guangxi were detected by multiplex SNaPshot and DNA sequencing method, and the blood lipid-related indexes were detected by 7600 biochemical analyzer. The distribution of rs2296616 C/T polymorphism among different ethnic groups and the differences of blood lipid levels among different genotypes were compared by statistical method . Results MiR-107 gene rs2296616 C/T SNP contained TT(91. 1%), CT (8. 9%)genotypes and T(95. 6%), C(4. 4%)alleles in Guangxi healthy population. The frequencies of genotype and allele distribution of rs2296616 C/T were not significantly different among genders in Guangxi population(P>0. 05). However, there were significant differences in the genotype and allele frequency of miR-107 gene rs2296616 C/T in Guangxi healthy population compared with those of Europeans, Japanese, Africans, Mexicans and Indians published in HapMap(P 0. 05). When compared the blood lipid level among two genotypes in rs2296616 C/T, we found that the level of high density lipoprotein cholesterol(HDL-C) with TT genotype was significantly different from that of CT group (P < 0. 05) . Conclusion There are different degrees of variation in the polymorphisms of rs2296616 C / T of miR-107 gene between Guangxi people and other ethnic populations. The polymorphism of rs2296616 C / T locus is related to the level of HDL-C.
