Genes affected

LRRFIP2 (HGNC:6703): (LRR binding FLII interacting protein 2) The protein encoded by this gene, along with MYD88, binds to the cytosolic tail of toll-like receptor 4 (TLR4), which results in activation of nuclear factor kappa B signaling. The ubiquitin-like protein FAT10 prevents the interaction of the encoded protein and TLR4, thereby inactivating the nuclear factor kappa B signaling pathway. In addition, this protein can downregulate the NLRP3 inflammasome by recruiting the caspase-1 inhibitor Flightless-I to the inflammasome complex. [provided by RefSeq, Jan 2017]

Ambry Genetics

Nov 11, 2024

The c.1034G>A (p.R345Q) alteration is located in exon 18 (coding exon 16) of the LRRFIP2 gene. This alteration results from a G to A substitution at nucleotide position 1034, causing the arginine (R) at amino acid position 345 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
