A leucine repeat in the carnosinase gene CNDP1 is associated with diabetic end-stage renal disease in European Americans

Abstract

European Americans homozygous for the 5-5 leucine repeat polymorphism in the CNDP1 gene are at significantly reduced risk for developing diabetic ESRD. This replicates the CNDP1 gene association with DN that was initially detected in European Caucasians and in Arabs, and further demonstrates that the CNDP1 gene and carnosine pathway appear to play a role in susceptibility to DN.
