Invitae RCV000535735 SCV000652332 uncertain significance Developmental and epileptic encephalopathy, 1; Autosomal recessive spinocerebellar ataxia 12 2017-10-16 criteria provided, single submitter clinical testing This variant is a gross duplication of the genomic region encompassing exons 1-8 of the WWOX gene. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 8 of the WWOX gene. This particular copy number variant has not been reported in the literature in individuals with a WWOX-related disease. Gross duplications that include at least part of the 5' end of the WWOX gene, and extend to adjacent genes, have been reported in individuals affected with autism spectrum disorder. However, some of these duplications were also reported in unaffected family members (PMID: 27569545). In summary, the exact genomic location of this variant is unknown and this variant has uncertain impact on WWOX function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
