TBX20 (T-box transcription factor TBX20) variants and mutations

TBX20 (also known as T-box transcription factor TBX20) is a human protein-coding gene encoding a t-box transcription factor protein. It controls transcriptional programs required for cardiac chamber formation, septation, conduction-system development, and adult myocardial function. Heterozygous pathogenic variants can cause congenital heart defects and dilated cardiomyopathy. This analysis covers 873 TBX20 variants and mutations. Of these, 76% have computational variant effect predictions. Disease context includes atrial septal defect, dilated cardiomyopathy, and atrial septal defect 1. Example TBX20 variants include E2K, F3L, and T4K.
