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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.047724664).
BS2
High AC in GnomAdExome4 at 11 Unknown,AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.88G>T (p.A30S) alteration is located in exon 1 (coding exon 1) of the IL17RC gene. This alteration results from a G to T substitution at nucleotide position 88, causing the alanine (A) at amino acid position 30 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces alanine with serine at codon 30 of the IL17RC protein (p.Ala30Ser). The alanine residue is weakly conserved and there is a moderate physicochemical difference between alanine and serine. This variant is present in population databases (rs756868871, ExAC 0.006%). This variant has not been reported in the literature in individuals with IL17RC-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -
