This sequence change replaces arginine with leucine at codon 424 of the NF2 protein (p.Arg424Leu). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and leucine. This variant is present in population databases (rs751182657, ExAC 0.02%). This variant has not been reported in the literature in individuals with a NF2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: Tolerated; PolyPhen-2: Possibly Damaging; Align-GVGD: Class C0). In summary, this variant has uncertain impact on NF2 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
