Neuronal ceroid lipofuscinosis Uncertain:1
This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 30 of the CLN3 protein (p.His30Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CLN3-related conditions. ClinVar contains an entry for this variant (Variation ID: 457955). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CLN3 protein function with a negative 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. -
