not specified Uncertain:1
Does not currently meet published gene-disease clinical validity criteria Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Epilepsy, progressive myoclonic, 1B Uncertain:1
This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 471 of the PRICKLE1 protein (p.Met471Thr). This variant is present in population databases (rs777597253, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with PRICKLE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 568656). 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 PRICKLE1 protein function with a negative predictive value of 80%. 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. -
