In a study by Barochia et al., HDL-C and apolipoprotein A1 (apoA-I) were positively correlated with FEV1, whereas LDL-C, triglycerides, apolipoprotein B (apoB), and the apoB/apoA-I ratio were negatively correlated with FEV1 among patients with atopic asthma [62]. The gene discussed is APOA1; the disease is atopic asthma.
