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.

Invitae

Nov 07, 2022

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the WWOX protein in which other variant(s) (p.Pro47Thr) have been determined to be pathogenic (PMID: 24369382). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with WWOX-related conditions. This variant is present in population databases (rs758588684, gnomAD 0.03%). This sequence change affects the initiator methionine of the WWOX mRNA. The next in-frame methionine is located at codon 114. -
