Relationship between Genetic Polymorphisms of the Gltathione S-transferase and Endometriosis Susceptibility in Korean Populations

Objective : The aim of this study was to examine whether polymorphic variation in GSTs confers susceptibility to Endometriosis in Korean populations. Methods : The GSTM1, GSTT1, and GSTP1 genotypes were determined in 124 patients with Endometriosis (stage 3, 4) and 155 healthy control subjects at Ewha woman's university Mok-dong hospital from 1996 to 2003. Results : The homozygous wild allele in GSTP1 gene was most common genotypes both Endometriosis and healthy control groups (69.4% vs. 64.5%). Neither the heterozygous nor homozygous mutant allele in GSTP1 gene differed in frequency between the two groups (30.6% vs 35.5%). When null mutations in GSTM1, GSTT1 were combined with GSTP1 polymorphism, there was no evidence of increase in the risk of endometriosis, as the number of high risk alleles of the GST family increased. Conclusion : Our findings suggest that GSTP1 genetic polymorphism may not be associated with development of Endometriosis in Korean populations. There is no evidence of a trend in increasing risk with the number of putative high risk alleles of the GST family carried.
