This gene encodes a homeobox-containing transcription factor. This transcription factor functions in heart formation and development. Mutations in this gene cause atrial septal defect with atrioventricular conduction defect, and also tetralogy of Fallot, which are both heart malformation diseases. Mutations in this gene can also cause congenital hypothyroidism non-goitrous type 5, a non-autoimmune condition. Alternative splicing results in multiple transcript variants.

A study in mice demonstrated that the NKX2-5 transcription factor is a key regulator of cardiac development and maturation, with its expression being down-regulated upon knockdown of the novel long non-coding RNA Novlnc6 in neonatal cardiomyocytes [Ounzain et al. DOI:10.1093/eurheartj/ehu180]. This research further identified the NKX2-5 as being significantly down-regulated in human dilated cardiomyopathy, and its spatial expression in the second heart field is directed by chemokine receptors Cxcr2 and Cxcr4 to guide cardiac progenitor migration [Yamada & Nomura DOI:10.3390/ijms21218345]. A study in rats demonstrated that cardiac fibroblasts exhibit age-dependent transcriptomic shifts, with principal component analysis showing data variance was predominantly due to developmental age [Perreault et al. DOI:10.1152/physiolgenomics.00074.2021].
