Invitae RCV000824069 SCV000964950 uncertain significance Developmental and epileptic encephalopathy, 1; Autosomal recessive spinocerebellar ataxia 12 2024-01-19 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 225 of the WWOX protein (p.Leu225Val). This variant is present in population databases (rs376040091, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with WWOX-related conditions. ClinVar contains an entry for this variant (Variation ID: 451480). 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 WWOX 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.
