Genes affected

IL17RA (HGNC:5985): (interleukin 17 receptor A) Interleukin 17A (IL17A) is a proinflammatory cytokine secreted by activated T-lymphocytes. It is a potent inducer of the maturation of CD34-positive hematopoietic precursors into neutrophils. The transmembrane protein encoded by this gene (interleukin 17A receptor; IL17RA) is a ubiquitous type I membrane glycoprotein that binds with low affinity to interleukin 17A. Interleukin 17A and its receptor play a pathogenic role in many inflammatory and autoimmune diseases such as rheumatoid arthritis. Like other cytokine receptors, this receptor likely has a multimeric structure. Alternative splicing results in multiple transcript variants encoding different isoforms.

IL17RA NM_014339.6 exon 13 p.Thr498Ile (c.1493C>T): This variant has not been reported in the literature but is present in 0.5% (146/24748) of African alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/22-17589602-C-T?dataset=gnomad_r2_1). This variant is present in ClinVar (Variation ID:476362). Evolutionary conservation suggests that this variant may not impact the protein; computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
