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.

Autosomal recessive spinocerebellar ataxia 12;C3463992:Developmental and epileptic encephalopathy, 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 27, 2022 | This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 200 of the WWOX protein (p.Lys200Arg). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 581945). 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: "Benign"; 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. - |
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 19, 2021 | The c.599A>G (p.K200R) alteration is located in exon 6 (coding exon 6) of the WWOX gene. This alteration results from a A to G substitution at nucleotide position 599, causing the lysine (K) at amino acid position 200 to be replaced by an arginine (R). The p.K200R alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
