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

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 22-17108749-C-T is Benign according to our data. Variant chr22-17108749-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 340600.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Benign=1, Uncertain_significance=1}. Variant chr22-17108749-C-T is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=0.038 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00211 (322/152364) while in subpopulation NFE AF= 0.00335 (228/68036). AF 95% confidence interval is 0.00299. There are 1 homozygotes in gnomad4. There are 151 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 4 AR gene
