Hemizygous deletions of a critical region largely overlapped by the current interval have been reported in association with a range of seizure phenotypes (Mucha 2019, Tinker 2020). Copy number losses involving this interval have a proposed but not established association with a clinical phenotype, and there are no similar copy number losses of this region in the general populations of the Database of Genomic Variants. Therefore, based on current medical literature, this copy number variant (CNV) is classified as likely pathogenic. References: Campeau et al., Lancet Neurol. 2014 Jan;13(1):44-58.
