Genes affected

WWOX (HGNC:12799): (WW domain containing oxidoreductase) This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) protein family. This gene spans the FRA16D common chromosomal fragile site and appears to function as a tumor suppressor gene. Expression of the encoded protein is able to induce apoptosis, while defects in this gene are associated with multiple types of cancer. Disruption of this gene is also associated with autosomal recessive spinocerebellar ataxia 12. Disruption of a similar gene in mouse results in impaired steroidogenesis, additionally suggesting a metabolic function for the protein. Alternative splicing results in multiple transcript variants.

This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 330 of the WWOX protein (p.Asn330Lys). This variant is present in population databases (rs117209694, gnomAD 0.03%). This missense change has been observed in individual(s) with Rolandic epilepsy (PMID: 29358611). ClinVar contains an entry for this variant (Variation ID: 433131). 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. 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. -

Identified in an individual with high HDL-C levels; however, no additional phenotype information was provided and a second WWOX variant was not identified (Motazacker et al., 2013); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 23685560, 29358611, 25411445) -
