Description

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 601 of the NF1 protein (p.Arg601Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of NF1-related conditions (PMID: 21520333). ClinVar contains an entry for this variant (Variation ID: 404478). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NF1 protein function with a positive predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
