Genes affected

TBKBP1 (HGNC:30140): (TBK1 binding protein 1) TBKBP1 is an adaptor protein that binds to TBK1 (MIM 604834) and is part of the interaction network in the TNF (MIM 191160)/NFKB (see MIM 164011) pathway (Bouwmeester et al., 2004 [PubMed 14743216]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.766C>T (p.R256W) alteration is located in exon 5 (coding exon 5) of the TBKBP1 gene. This alteration results from a C to T substitution at nucleotide position 766, causing the arginine (R) at amino acid position 256 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
