Genes affected

IL17RD (HGNC:17616): (interleukin 17 receptor D) This gene encodes a membrane protein belonging to the interleukin-17 receptor (IL-17R) protein family. The encoded protein is a component of the interleukin-17 receptor signaling complex, and the interaction between this protein and IL-17R does not require the interleukin. The gene product also affects fibroblast growth factor signaling, inhibiting or stimulating growth through MAPK/ERK signaling. Alternate splicing generates multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jan 2016]

Ambry Genetics

Apr 18, 2023

The c.2009C>T (p.P670L) alteration is located in exon 12 (coding exon 12) of the IL17RD gene. This alteration results from a C to T substitution at nucleotide position 2009, causing the proline (P) at amino acid position 670 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant is present in population databases (rs143119752, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 670 of the IL17RD protein (p.Pro670Leu). This variant has not been reported in the literature in individuals affected with IL17RD-related conditions. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt IL17RD protein function. ClinVar contains an entry for this variant (Variation ID: 1442770). -
