Summaries for TBX5 Gene

Entrez Gene Summary for TBX5 Gene

  • This gene is a member of a phylogenetically conserved family of genes that share a common DNA-binding domain, the T-box. T-box genes encode transcription factors involved in the regulation of developmental processes. This gene is closely linked to related family member T-box 3 (ulnar mammary syndrome) on human chromosome 12. The encoded protein may play a role in heart development and specification of limb identity. Mutations in this gene have been associated with Holt-Oram syndrome, a developmental disorder affecting the heart and upper limbs. Several transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jul 2008]

Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Defects in TBX5 are associated with susceptibility to heart disorders including dilated cardiomyopathy (DCM) and atrial fibrillation (AF). DCM is characterized by ventricular and impaired systolic function, resulting in heart failure and arrhythmia. Patient are at risk of premature death. AF is a common sustained cardiac rhythm disturbance. AF is characterized by disorganized atrial electrical activity and ineffective atrial contraction promoting blood stasis in the atria and reduces ventricular filling. It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure. {ECO:0000269 PubMed:25725155, ECO:0000269 PubMed:25963046, ECO:0000269 PubMed:26917986, ECO:0000269 PubMed:27035640}.
