[CYP1A1 rs4646422 gene polymorphisms not correlated with male infertility in Chinese Han population]
Objective:
To determine the correlation of the CYP1A1 (rs4646422) gene polymorphisms with male infertility in the Chinese Han population.
Methods:
Using the Mass ARRAY iPLEX GOLD technique, we conducted a case-control study on theCYPlA1 (rs4646422) gene polymorphisms in 636 infertile males aged 21-49 years (case group) and 442 normal healthy men aged 23-47 years (control group) of the Chinese Han population. We analyzed the genotypes and allele frequencies in the two groups ofsubjects with the SPSS 20.0 software.
Results:
Compared with the wild homozygous genotype GG, the heterozygous genotype AG (OR = 1.06, 95% CI 0.81-1.38) and homozygous genotype AA (OR = 1.11, 95% CI 0.56-2.21) showed no correlation with male infertility, nor did the mutant allele A (OR = 1.06, 95% CI 0.85-1.32) in comparison with the wild allele G.
Conclusion:
The CYP1A1 (rs4646422) gene polymorphisms might not be correlated with male infertility in the Chinese Han population.
