Genes affected

TNFAIP6 (HGNC:11898): (TNF alpha induced protein 6) The protein encoded by this gene is a secretory protein that contains a hyaluronan-binding domain, and thus is a member of the hyaluronan-binding protein family. The hyaluronan-binding domain is known to be involved in extracellular matrix stability and cell migration. This protein has been shown to form a stable complex with inter-alpha-inhibitor (I alpha I), and thus enhance the serine protease inhibitory activity of I alpha I, which is important in the protease network associated with inflammation. This gene can be induced by proinflammatory cytokines such as tumor necrosis factor alpha and interleukin-1. Enhanced levels of this protein are found in the synovial fluid of patients with osteoarthritis and rheumatoid arthritis.[provided by RefSeq, Dec 2010]

Ambry Genetics

Mar 07, 2024

The c.402G>C (p.E134D) alteration is located in exon 4 (coding exon 4) of the TNFAIP6 gene. This alteration results from a G to C substitution at nucleotide position 402, causing the glutamic acid (E) at amino acid position 134 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
