| pubmed-article:20518838 | pubmed:abstractText | The precise cause of vitiligo is unknown. However, autoimmunity is considered the most likely aetiology, especially in nonsegmental vitiligo (NSV). In this study we determined whether or not the transforming growth factor beta receptor II (TGFBR2) gene contributes to susceptibility for NSV in the Korean population. Blood samples were collected from 415 controls and 233 cases. We selected three single nucleotide polymorphisms (SNPs) in the TGFBR2 gene. The genotypes of the SNPs were determined using direct sequencing. All of the SNPs were significantly different between the vitiligo patients and controls (rs2005061, co-dominant, dominant, recessive, P < 0.05; rs3773645, co-dominant, dominant, recessive, P < 0.05; rs3773649, co-dominant, recessive, P < 0.05). In addition, haplotype 1 (CG) and haplotype 2 (GA) of the linkage disequilibrium (LD) block were also associated with a risk of NSV. The present study suggests that TGFBR2 might be related to NSV. | lld:pubmed |
