Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TBX5 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000181486.4. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: DNA-binding protein that regulates the transcription of several genes and is involved in heart development and limb pattern formation (PubMed:25725155, PubMed:25963046, PubMed:29174768, PubMed:26917986, PubMed:27035640, PubMed:8988164). Binds to the core DNA motif of NPPA promoter (PubMed:26926761). {ECO:0000269|PubMed:25725155, ECO:0000269|PubMed:25963046, ECO:0000269|PubMed:26917986, ECO:0000269|PubMed:26926761, ECO:0000269|PubMed:27035640, ECO:0000269|PubMed:29174768, ECO:0000269|PubMed:8988164}.;
Disease
DISEASE: Holt-Oram syndrome (HOS) [MIM:142900]: Developmental disorder affecting the heart and upper limbs. It is characterized by thumb anomaly and atrial septal defects. {ECO:0000269|PubMed:10077612, ECO:0000269|PubMed:10842287, ECO:0000269|PubMed:12818525, ECO:0000269|PubMed:15735645, ECO:0000269|PubMed:20450920, ECO:0000269|PubMed:8988164, ECO:0000269|PubMed:8988165}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: 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}.;
