Description

The p.A1828T variant (also known as c.5482G>A), located in coding exon 27 of the SCN5A gene, results from a G to A substitution at nucleotide position 5482. The alanine at codon 1828 is replaced by threonine, an amino acid with similar properties. This variant has been detected in a dilated cardiomyopathy cohort (Mazzarotto F et al. Circulation. 2020 Feb;141(5):387-398). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
