Different Roles of TP53 Codon 72 Polymorphism in Type 2 Diabetes and Its Complications: Evidence from a Case-Control Study on a Chinese Han Population.

There was a significant association of the TP53 Pro72Arg polymorphism with susceptibility to T2DM, and the homozygous Arg/Arg genotype of this gene locus might be a protective factor for diabetic complications. Those results suggested that the TP53 Arg72 variant had a different association with type 2 diabetes and its complications, and it might be related to mtDNA maintenance of the TP53 Arg72 variant under hyperglycemia-induced stress.
