Objectives C1858T single nucleotide polymorphism in PTPN22 encoding the R620W allele
variant of Lyp-PTPN22 (a protein phosphatase negatively regulating T-cell activation) has
been associated with autoimmunity. This work has investigated the possible association
between PTPN22 C1858T (rs2476601) polymorphism and rheumatoid arthritis (RA),
systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) in a Colombian
population.
