Abstract
Objective
The peroxisome proliferator–activated receptor-γ (PPAR-γ) is a nuclear hormone receptor that plays an important role in many diseases. This study investigated whether two polymorphisms (Pro12Ala in exon B and C161T in exon 6) of the PPAR-γ2 gene are related to adenomyosis, endometriosis, or leiomyomata.
Methods
A total of 390 patients with adenomyosis, endometriosis, and/or leiomyomata were classified into four groups: 103 patients with adenomyosis (21 adenomyosis only and 82 adenomyosis with endometriosis and/or leiomyomata), 95 patients with endometriosis only, 100 patients with leiomyomata only, and 92 patients with endometriosis and leiomyomata.
Results
There was no association between distribution of genotype or allele frequencies for the PPAR-γ Pro12Ala polymorphism and the presence of adenomyosis, endometriosis, and/or leiomyomata. However, compared with results for controls, the PPAR-γ 161CC genotype and 161C allele frequencies were significantly increased in patients with adenomyosis (genotype: X2 = 8. 185, corrected P value [Pc] =. 0169; allele: X2 = 8. 331, Pc =. 0155) and inpatients with endometriosis (genotype: X2 = 6. 748, Pc =. 0375; allele: X2 = 6. 413, Pc =. 0453).
Conclusion
The results suggest that the PPAR-γ 161CC genotype could be a genetic risk factor for adenomyosis and endometriosis, whereas the Pro12Ala polymorphism was not associated with these estrogen-dependent benign uterine diseases in a fapanese population.
