Description

The p.A419T variant (also known as c.1255G>A), located in coding exon 12 of the PRKAG2 gene, results from a G to A substitution at nucleotide position 1255. The alanine at codon 419 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. 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.
