The p.D559Y variant (also known as c.1675G>T), located in coding exon 15 of the NF2 gene, results from a G to T substitution at nucleotide position 1675. The aspartic acid at codon 559 is replaced by tyrosine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. 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.
