Genes affected

TOLLIP (HGNC:16476): (toll interacting protein) This gene encodes a ubiquitin-binding protein that interacts with several Toll-like receptor (TLR) signaling cascade components. The encoded protein regulates inflammatory signaling and is involved in interleukin-1 receptor trafficking and in the turnover of IL1R-associated kinase. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2016]

The c.449A>G (p.K150R) alteration is located in exon 4 (coding exon 4) of the TOLLIP gene. This alteration results from a A to G substitution at nucleotide position 449, causing the lysine (K) at amino acid position 150 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
