FOXP4 and pulmonary emphysema: Ani Manichaikul et al. [30] conducted a GWAS of subclinical interstitial lung disease (ILD) in the population-based Multi-Ethnic Study of Atherosclerosis Study, which reported a novel FOXP4 region variant rs2894439 associated with emphysema and in LD with the lead variants rs1886814 (r2 = 0.7) [29], suggesting a potential role of this gene in disease severity.
