TBX5 (T-box transcription factor TBX5) variants and mutations

TBX5 (also known as T-box transcription factor TBX5) is a human protein-coding gene encoding a t-box transcription factor protein. It directs upper-limb and cardiac developmental programs and later helps maintain cardiac conduction gene expression. Haploinsufficiency causes Holt-Oram syndrome, characterized by radial-ray limb abnormalities and congenital heart or conduction defects. This analysis covers 1,246 TBX5 variants and mutations. Of these, 66% have computational variant effect predictions. Disease context includes Holt-Oram syndrome, aortic valve disease 2, and atrial fibrillation. Example TBX5 variants include M1?, A2G, and A2T.
