Association of PTPN22 gene polymorphism with type 1 diabetes mellitus in Chinese children and adolescents
Previous studies have indicated that the protein tyrosine phosphatase nonreceptor type 22 gene (PTPN22) is associated with type 1 diabetes (T1DM) in the Caucasian population. In the present study, we investigated the relationship between PTPN22 genetic polymorphisms and T1DM in Chinese children. A total of 202 children and adolescents with T1DM and 240 healthy control subjects of Chinese Han origin were included in our analysis.
