Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM5PP3_Moderate
The NM_016373.4(WWOX):c.715C>G(p.Leu239Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000062 in 1,614,062 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L239R) has been classified as Likely pathogenic.

Autosomal recessive spinocerebellar ataxia 12;C3463992:Developmental and epileptic encephalopathy, 1    Uncertain:1 
This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 239 of the WWOX protein (p.Leu239Val). This variant is present in population databases (rs575080327, gnomAD 0.0009%). 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: 473030). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). 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. -
