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.

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BP6: Variant 22-17108626-C-T is Benign according to our data. Variant chr22-17108626-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 340597.
• BP7: Synonymous conserved (PhyloP=0.133 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00123 (187/152340) while in subpopulation NFE AF = 0.00128 (87/68020). AF 95% confidence interval is 0.00106. There are 1 homozygotes in GnomAd4. There are 117 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 4 AD,AR gene
