CYSLTR1 and asthma: For example, the gene CYSLTR1 is linked to asthma in the text of the Gene Wiki: “The cysteinyl leukotrienes...] are important mediators of human bronchial asthma” and in the text of the SNPedia article on rs320995 (a SNP found in the CYSLTR1 gene): “subjects without T-allele in SNP rs320995 had 3.1 times higher risk of asthma” [21].
