Genes affected

IL17RC (HGNC:18358): (interleukin 17 receptor C) This gene encodes a single-pass type I membrane protein that shares similarity with the interleukin-17 receptor (IL-17RA). Unlike IL-17RA, which is predominantly expressed in hemopoietic cells, and binds with high affinity to only IL-17A, this protein is expressed in nonhemopoietic tissues, and binds both IL-17A and IL-17F with similar affinities. The proinflammatory cytokines, IL-17A and IL-17F, have been implicated in the progression of inflammatory and autoimmune diseases. Multiple alternatively spliced transcript variants encoding different isoforms have been detected for this gene, and it has been proposed that soluble, secreted proteins lacking transmembrane and intracellular domains may function as extracellular antagonists to cytokine signaling.

The c.1312C>G (p.L438V) alteration is located in exon 12 (coding exon 12) of the IL17RC gene. This alteration results from a C to G substitution at nucleotide position 1312, causing the leucine (L) at amino acid position 438 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 438 of the IL17RC protein (p.Leu438Val). This variant is present in population databases (rs773903331, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with IL17RC-related conditions. ClinVar contains an entry for this variant (Variation ID: 542530). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
