Genes affected

TAB3 (HGNC:30681): (TGF-beta activated kinase 1 (MAP3K7) binding protein 3) The product of this gene functions in the NF-kappaB signal transduction pathway. The encoded protein, and the similar and functionally redundant protein MAP3K7IP2/TAB2, forms a ternary complex with the protein kinase MAP3K7/TAK1 and either TRAF2 or TRAF6 in response to stimulation with the pro-inflammatory cytokines TNF or IL-1. Subsequent MAP3K7/TAK1 kinase activity triggers a signaling cascade leading to activation of the NF-kappaB transcription factor. The human genome contains a related pseudogene. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

The c.986C>T (p.P329L) alteration is located in exon 6 (coding exon 2) of the TAB3 gene. This alteration results from a C to T substitution at nucleotide position 986, causing the proline (P) at amino acid position 329 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
