Gene: IL17A
I agree that the level should be reviewed for being increased to Green especially the association of SNPs with H1N1 (influenza A) and influenza B.
Association with CNVs with pathology has been confirmed but the disease state was not revealed in any of the patients

Comment on list classification: Promoted from Red to Amber. There appears to be enough evidence for this gene to be promoted Green; however, will wait for expert review before promoting to Green.Created: 7 Apr 2020, 9:10 a.m. | Last Modified: 7 Apr 2020, 9:10 a.m.

IL-17A is important for protection from bacterial, fungal and viral infections in the mucosal tracts. Aberrant expression or over expression of IL-17 causes a range of outcomes: asthma, lung inflammation and lung fibrosis (PMID: 28860146).
PMID: 31196204 is a case-control study that looked at 50 H1N1 (influenza A), 30 influenza B and 96 influenza-like illness (ILI) confirmed Iranian cases. The rs2275913 SNP in IL-17 increased the risk of H1N1 infection (P=0.008). PMID: 27155288 also found rs2275913 is asosicated with risk of infection by H3N2 (P < 0.05, OR = 2.08-2.94).
PMID: 27890033 investigated patients who had acute brochiolitis (from mild to severe respiratory failure) in Brazil. The study found that IL-17 rs2275913 SNP showed significant association with acute brochiolitis severity (P<0.001).
PMID: 21703407 showed that mice infected with respiratory syncytial virus (RSV) and treated with anti-IL-17 had reduced inflammation and decreased viral load compared to control mice. Blocking IL-17 during infection significantly increased RSV specific CD8 T cells, and factors associated with CD8 T cells cytotoxicity were significantly upregulated.
PMID: 29530464 showed that IL-17A expression may be involved with the development and severity of viral myocarditis (VMC). The SNP rs2275913 might influence on susceptibility to VMC.Created: 7 Apr 2020, 8:45 a.m. | Last Modified: 7 Apr 2020, 8:45 a.m.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.Created: 20 Apr 2018, 12:25 p.m.
