Description

The p.A143T variant (also known as c.427G>A), located in coding exon 4 of the TBX5 gene, results from a G to A substitution at nucleotide position 427. The alanine at codon 143 is replaced by threonine, an amino acid with similar properties. This variant has been detected in an individual with dilated cardiomyopathy (Zhou W et al. Int J Mol Med, 2015 Jul;36:282-8). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear.
