NCIt definition : Human PTPN22 wild-type allele is located within 1p13.3-p13.1 and is approximately
123 kb in length. This allele, which encodes tyrosine-protein phosphatase non-receptor
type 22 protein, plays a role in the dephosphorylation of protein-tyrosine phosphates.
Functional PTPN22 gene polymorphisms are associated with susceptibility to insulin-dependent
diabetes mellitus, rheumatoid arthritis, systemic lupus erythematosus, and Hashimoto
thyroiditis.;
