Autosomal recessive spinocerebellar ataxia 12;C3463992:Developmental and epileptic encephalopathy, 1 Uncertain:1
This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 377 of the WWOX protein (p.Asn377Lys). This variant is present in population databases (rs377129275, gnomAD 0.01%). 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: 540234). 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 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. -
Inborn genetic diseases Uncertain:1
The c.1131C>A (p.N377K) alteration is located in exon 9 (coding exon 9) of the WWOX gene. This alteration results from a C to A substitution at nucleotide position 1131, causing the asparagine (N) at amino acid position 377 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
