FcɛR1α gene polymorphism shows association with high IgE and anti‐FcɛR1α in Chronic Rhinosinusitis with Nasal Polyposis
AssociationN=282Sajad A. Dar et al.(2018)· Journal of Cellular Biochemistry

A retrospective cohort study of 282 patients with severe uncontrolled asthma treated with omalizumab, mepolizumab, or benralizumab for 12 months evaluated genetic variants in 11 genes (IL1RL1, IL5, GATA2, IKZF2, RAD50, C3, FCER1A, FCER1B, FCGR2A, FCGR2B, FCGR3A) as predictors of response. Key findings: FCGR2B rs3219018-C, GATA2 rs4857855-T, and FCGR2A rs1801274-AG associated with improved lung function in omalizumab (p=0.052, 0.052, 0.012); IL1RL1 rs17026974-AG/GG associated with reduced exacerbations in omalizumab (p=0.040, 0.041); FCER1B rs569108-AA and FCGR2A rs1801274-GG associated with corticosteroid reduction in benralizumab; FCER1A rs2427837-A associated with improved lung function in mepolizumab (p=0.023).

About IL1RL1

The protein encoded by this gene is a member of the interleukin 1 receptor family. Studies of the similar gene in mouse suggested that this receptor can be induced by proinflammatory stimuli, and may be involved in the function of helper T cells. This gene, interleukin 1 receptor, type I (IL1R1), interleukin 1 receptor, type II (IL1R2) and interleukin 1 receptor-like 2 (IL1RL2) form a cytokine receptor gene cluster in a region mapped to chromosome 2q12. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]
