Description

The p.I273V variant (also known as c.817A>G), located in coding exon 9 of the NF2 gene, results from an A to G substitution at nucleotide position 817. The isoleucine at codon 273 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
