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.154G>A (p.V52M) alteration is located in exon 2 (coding exon 2) of the TOLLIP gene. This alteration results from a G to A substitution at nucleotide position 154, causing the valine (V) at amino acid position 52 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
