PTPN22

protein-coding

protein tyrosine phosphatase non-receptor type 22, the group of Protein tyrosine phosphatases non-receptor type

Gene summary

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]

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_015967.8. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

Function
FUNCTION: Acts as negative regulator of T-cell receptor (TCR) signaling by direct dephosphorylation of the Src family kinases LCK and FYN, ITAMs of the TCRz/CD3 complex, as well as ZAP70, VAV, VCP and other key signaling molecules (PubMed:16461343, PubMed:18056643). Associates with and probably dephosphorylates CBL. Dephosphorylates LCK at its activating 'Tyr-394' residue (PubMed:21719704). Dephosphorylates ZAP70 at its activating 'Tyr- 493' residue (PubMed:16461343). Dephosphorylates the immune system activator SKAP2 (PubMed:21719704). Positively regulates toll-like receptor (TLR)-induced type 1 interferon production (PubMed:23871208). Promotes host antiviral responses mediated by type 1 interferon (By similarity). Regulates NOD2-induced pro- inflammatory cytokine secretion and autophagy (PubMed:23991106). {ECO:0000250|UniProtKB:P29352, ECO:0000269|PubMed:16461343, ECO:0000269|PubMed:18056643, ECO:0000269|PubMed:19167335, ECO:0000269|PubMed:21719704, ECO:0000269|PubMed:23871208, ECO:0000269|PubMed:23991106}.;
Disease
DISEASE: Systemic lupus erythematosus (SLE) [MIM:152700]: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow. {ECO:0000269|PubMed:15273934}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: Diabetes mellitus, insulin-dependent (IDDM) [MIM:222100]: A multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical features are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels. {ECO:0000269|PubMed:15004560}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: Rheumatoid arthritis (RA) [MIM:180300]: An inflammatory disease with autoimmune features and a complex genetic component. It primarily affects the joints and is characterized by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. {ECO:0000269|PubMed:15208781}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: Vitiligo (VTLG) [MIM:193200]: A pigmentary disorder of the skin and mucous membranes. It is characterized by circumscribed depigmented macules and patches, commonly on extensor aspects of extremities, on the face or neck and in skin folds. Vitiligo is a progressive disorder in which some or all of the melanocytes in the affected skin are selectively destroyed. It is a multifactorial disorder with a complex etiology probably including autoimmune mechanisms, and is associated with an elevated risk of other autoimmune diseases. {ECO:0000269|PubMed:16015369}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.;
