Labcorp Genetics (formerly Invitae), Labcorp RCV001383151 SCV001582191 pathogenic Developmental and epileptic encephalopathy, 2; Angelman syndrome-like 2021-07-13 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with CDKL5-related conditions. This variant is a gross deletion of the genomic region encompassing exon(s) 4-21 of the CDKL5 gene. The 5' boundary is likely confined to intron 3. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product or disrupt mRNA translation. For these reasons, this variant has been classified as Pathogenic. The region of the CDKL5 gene that includes exon(s) 10 has been determined to be clinically significant (PMID: 22867051). Therefore, deletions that encompass that region are likely to disrupt protein function and cause disease.
