Problem To investigate the association between endometriosis, transforming growth factor-beta 1 (TGFB1) gene polymorphisms, and serum TGF-beta 1 levels in Korean women. Method of study The) 509C/T, 868T/C, 913G/C and 979G/A polymorphisms of the TGFB1 gene were analyzed in women with (n = 131) and without (n = 107) endometriosis using restriction fragment length polymorphism (RFLP) analysis. Serum TGF-b1 levels were measured by enzyme-linked immunosorbent assay (ELISA). Results The 913G/C and 979G/A polymorphisms were not observed in the study participants. The genotype and allele distribution of the) 509C/T and 868T/C polymorphisms in endometriosis were similar to those in controls. However, the) 509T/868C (TC) haplotype allele was observed 4.55 times more frequently in early-stage endometriosis than in other haplotype alleles. Serum TGF-beta 1 levels were significantly higher in endometriosis than in controls. The single and haplotype genotype of) 509C/T and 868T/C polymorphisms were not related with serum TGF-beta 1 levels. Conclusion The TC haplotype allele of TGFB1) 509C/T and 868T/C polymorphisms may be associated with early-stage endometriosis in Korean women.
