Genes affected

TNIP1 (HGNC:16903): (TNFAIP3 interacting protein 1) This gene encodes an A20-binding protein which plays a role in autoimmunity and tissue homeostasis through the regulation of nuclear factor kappa-B activation. Mutations in this gene have been associated with psoriatic arthritis, rheumatoid arthritis, and systemic lupus erythematosus. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

The c.1370C>T (p.T457M) alteration is located in exon 13 (coding exon 12) of the TNIP1 gene. This alteration results from a C to T substitution at nucleotide position 1370, causing the threonine (T) at amino acid position 457 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
