Description

This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 67 of the GRIN1 protein (p.His67Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GRIN1-related conditions. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on GRIN1 protein function. 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.
