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, which is neutral and polar, with lysine, which is basic and polar, at codon 29 of the NPRL3 protein (p.Gln29Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with NPRL3-related conditions. ClinVar contains an entry for this variant (Variation ID: 568625). 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 not expected to disrupt NPRL3 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. -
