Genes affected

PTPN22 (HGNC:9652): (protein tyrosine phosphatase non-receptor type 22) 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]

The c.2378C>T (p.S793L) alteration is located in exon 21 (coding exon 21) of the PTPN22 gene. This alteration results from a C to T substitution at nucleotide position 2378, causing the serine (S) at amino acid position 793 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
