Because current knowledge on the CNDP1 genotypes in the Chinese population is still fragmentary, this study was conducted to delineate the distribution of CNDP1 genotypes, with focus on relevant polymorphisms reported to affect disease course of—or susceptibility to DN and their potential association with biomarkers of renal function or other metabolic parameters in a nondiabetic Chinese population. Here, CNDP1 is linked to liver dysplastic nodule.
