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]

The c.1179G>C (p.K393N) alteration is located in exon 20 (coding exon 18) of the LRRFIP2 gene. This alteration results from a G to C substitution at nucleotide position 1179, causing the lysine (K) at amino acid position 393 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
