GATA4 and coronary artery disorder: Previous study found in the tissues of heart and blood, one recognized single‐nucleotide polymorphism (SNP) (rs2277923) in NKX2‐5 and one recognized SNP (rs56166237) in GATA4. In contrast to our study, their study presented that NKX2‐5 and GATA4 mutations have no role in sporadic CHD pathogenesis (Yin et al., 2018).
