Description

The p.E277Q variant (also known as c.829G>C), located in coding exon 6 of the GDAP1 gene, results from a G to C substitution at nucleotide position 829. The glutamic acid at codon 277 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species; however, glutamine is the reference amino acid in other 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.
