NKX2-5 (Homeobox protein Nkx-2.5) variants and mutations

NKX2-5 (also known as Homeobox protein Nkx-2.5) is a human protein-coding gene encoding a homeobox protein Nkx-2.5 protein. It specifies myocardial lineages and maintains genes needed for adult conduction and contractile function. Heterozygous pathogenic variants can cause congenital heart defects, especially atrial septal defects, often with progressive conduction disease. This analysis covers 920 NKX2-5 variants and mutations. Of these, 84% have computational variant effect predictions. Disease context includes Atrial septal defect - atrioventricular conduction defects, atrial septal defect 7, and Tetralogy of Fallot. Example NKX2-5 variants include M1K, S4G, and S4N.
