TNFR 2 M196R polymorphism and acne vulgaris in Han Chinese: a case-control study.
In this case-control study, the relationship between M196R (676 T-->G) variant in exon 6 of tumor necrosis factor receptor type 2 (TNFR2) gene and genetic susceptibility of acne vulgaris in Han Chinese was investigated. A total of 93 acne vulgaris patients and 90 healthy subjects from Han Chinese ethnic group were enrolled in this study. ⋯ The results showed that there was significant difference in the frequency of the genotype M/R+R/R in the TNFR2 M196R genetic polymorphisms between acne vulgaris patients and healthy controls (chi2=4.343; P=0.037; OR=1.899; 95% CI: 1.036-3.445); and there was significant difference in the allele (R) frequency between acne vulgaris patients and healthy controls (chi2=5.588; P=0.018; OR=1.838; 95% CI: 1.105-3.057). It was concluded that the high frequency of 196R allele in the functional M196R polymorphism of TNFR2 is a risk factor for acne vulgaris in Han Chinese.
