Aim: Hyperplasia suppressor gene/mitofusion-2 (HSG/Mfn2) is a hyperplasia suppressor gene and an essential component of mitochondrial fusion machinery; however, the association between the single nucleotide polymorphism (SNP) of HSG/Mfn2 and hypertension is unclear.
Methods: In this study, 542 normotensive subjects (NT group) and 539 hypertensive patients (EH group) were screened for an association study between HSG/Mfn2 and hypertension.
Results: The results showed that the genotype distribution and allelic frequency of rs873457, rs2336384, rs1474868, rs4846085 and rs2236055 were significantly different (p lt; 0.05 for all) between EH and NT groups, although those of rs4240897 and rs873458 were not. When comparing the dominant model, significant differences still existed (p lt; 0.05 for all). The allelic frequency of rs4240897 was also slightly different between EH and NT groups (P=0.047). When subgrouped by sex, the genotype distribution and allelic frequency of all the SNPs (except rs873458) were significantly different in male (p lt; 0.05 for all) but not in female groups. For all the SNPs, only the allelic frequency of rs4240897 was obviously different in female NT and EH groups (p lt; 0.01). Logistic regression showed that body mass index and rs873457 were closely associated with BP after adjusting for age. The frequency of the C-G-A-A-A-C-C haplotype was significantly higher in essential hypertensive patients versus control individuals, both in the entire population, in male or female groups (p lt; 0.01 for all). As for other haplotypes, most were only significantly different in the entire population and male subjects.
Conclusion: The genetic variations of HSG/Mfn2 may be associated with hypertension in male Chinese.
