Disease
[TBX5_HUMAN] Holt-Oram syndrome. The disease is caused by mutations affecting the gene represented in this entry. Defects in TBX5 are associated with susceptibility to dilated cardiomyopathy (DCM). A disorder characterized by ventricular and impaired systolic function, resulting in heart failure and arrhythmia. Patient are at risk of premature death.[1] [2] [NKX25_HUMAN] Athyreosis;Familial isolated congenital asplenia;Atrial septal defect - atrioventricular conduction defects;Atrial septal defect, ostium secundum type;Hypoplastic left heart syndrome;Tetralogy of Fallot;Familial atrial fibrillation;Familial progressive cardiac conduction defect;Thyroid hypoplasia;Ventricular septal defect.

Function
[TBX5_HUMAN] DNA-binding protein that regulates the transcription of several genes and is involved in heart development and limb pattern formation.[3] [4] [5] [NKX25_HUMAN] Implicated in commitment to and/or differentiation of the myocardial lineage. Acts as a transcriptional activator of ANF in cooperation with GATA4 (By similarity). It is transcriptionally controlled by PBX1 and acts as a transcriptional repressor of CDKN2B (By similarity). It is required for spleen development.[6]
