As one part of the overall' aim for searching possible genetic markers that may play the important role on the development of IgA nephropathy, the authors investigated the association between one single nucleotide polymorphism (SNP), rs1982073, in the transforming growth factor beta 1 (TGFB1) gene and IgA nephropathy. The result showed, frequencies of selected SNP, rs1982073, was found to significantly differ between male patients and male controls in a codominant model (corrected p or
