Genetics studies primarily indicate markers for genes involved in immune system response and metabolism pathways that impact workers’ prevalence of isocyanate-asthma, including HLA serotypes, GST genes, NAT genes, and TGF-α (Bignon et al., 1994; Balboni et al., 1996; Mapp et al., 2000, 2002; Piirilä et al., 2001; Wikman et al., 2002; Beghé et al., 2004; Kim et al., 2006; Choi et al., 2009; Yucesoy et al., 2012, 2014, 2015, 2016). Here, BRD2 is linked to asthma.
