Description

The p.W279C variant (also known as c.837G>T), located in coding exon 3 of the GAA gene, results from a G to T substitution at nucleotide position 837. The tryptophan at codon 279 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
