Genes affected

NPRL3 (HGNC:14124): (NPR3 like, GATOR1 complex subunit) Contributes to GTPase activator activity. Involved in cellular response to amino acid starvation and negative regulation of TOR signaling. Located in lysosomal membrane. Part of GATOR1 complex. Implicated in focal epilepsy. [provided by Alliance of Genome Resources, Apr 2022]

This sequence change replaces glutamine with histidine at codon 405 of the NPRL3 protein (p.Gln405His). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and histidine. This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with clinical features of NPRL3-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 476216). 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 NPRL3 protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
