[Association of the C1858T polymorphism of the PTPN22 gene with type 1 diabetes].
To study the association with diabetes mellitus type 1 (T1DM) we performed TDT analysis and analysis of the distribution of frequencies of alleles and genotypes of polymorphic marker C1858T of the PTPN22 gene, encoding tyrosine phosphatase of non-receptor type (LYP). Groups of concordant (27 families) and discordant (62 families) sibpairs and groups of T1DM patients and unrelated controls of Russian origin were recruited in Endocrinology Research Center, Moscow and Center of Diabetes, Samara. For a given polymorphic marker was not found statistically significant associations with type 1 diabetes in the transmission disequilibrium test, while analysis of the distribution of frequencies of alleles and genotypes showed the association with T1DM. Thus, the polymorphic marker C1858T of the PTPN22 gene is associated with T1DM in Russian patients.
