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.

Uncertain significance, criteria provided, single submitter	clinical testing	Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago	Mar 30, 2021	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. -
