Gene annotation of SNPs associated with the effect of fat-free mass on asthma identified missense variants in ectonucleotide pyrophosphatase/phosphodiesterase 2 (ENPP2), nuclear receptor corepressor 2 (NCOR2), apoptosis associated tyrosine kinase (AATK), and POC5; 3’UTR variants in zinc finger CCCH-type containing 4 (ZC3H4), small nuclear ribonucleoprotein 13 (SNU13), FAIM2, tumor protein p53 (TP53), and lysine demethylase 2A (KDM2A); and intronic variants in other genes (Supplementary File S5). This evidence concerns the gene ZC3H4 and asthma.
