Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP6BS2
The NM_000268.4(NF2):c.1397G>A(p.Arg466Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,422,436 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R466L) has been classified as Uncertain significance.

The p.R466Q variant (also known as c.1397G>A), located in coding exon 13 of the NF2 gene, results from a G to A substitution at nucleotide position 1397. The arginine at codon 466 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly conserved in available 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. -
