Abstract:

AbstractObjectiveTo explore the relationship between the UCP1 gene -3826 A>G locus polymorphism and body mass index BMIin college students. Methods308 college students were randomly selectedand the genomic DNA were extracted from exfoliated cells of oral mucosa. The height and body weight of the subjects were recorded. The polymorphism of UCP1 gene -3826 A >G locus was detected by KASP technology. The genotype frequenciesallele frequencies and the relationship between different genotypes and BMI were statistically analyzed. ResultsAmong the 308 subjectsincluding 96 cases31.2%were male and 212 cases68.8%were female64 cases 20.8%)  were AA genotype wild type), 216 cases 70.1%were AG genotype heterozygous variant), and 28 cases9.1%were GG genotypehomozygous variant. There was no statistical significance in the composition ratio of genotypes between different genders. The mutation frequency of UCP1 gene -3836 A>G locus increased with the increase of BMIand the difference was statistically significant P<0.05); the risk assessment showed that the GG genotype increased the risk of body weight increase by 3.875 times compared with the normal group. ConclusionThe results indicated that the UCP1 gene-3826 A>G locus polymorphism was associated with the BMIthe homozygous variant at this locus will increase the risk of body weight increase.
