Protein tyrosine phosphatase, non-receptor type 22

PTPN22, LYP
This gene encodes of member of the non-receptor class 4 subfamily of the protein-tyrosine phosphatase family. The encoded protein is a lymphoid-specific intracellular phosphatase that associates with the molecular adapter protein CBL and may be involved in regulating CBL function in the T-cell receptor signaling pathway. Mutations in this gene may be associated with a range of autoimmune disorders including Type 1 Diabetes, rheumatoid arthritis, systemic lupus erythematosus and Graves' disease. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Mar 2009] (from NCBI)

Polymorphisms in the TNF-α(rs1800629), CTLA-4 (rs231775), and PTPN22 (rs2476601) genes have been previous associated with T1D; however, there is no consensus regarding their role in T1D and scarce literature focusing on AIDT and/or CD.
