Invitae | RCV001031684 | SCV001194990 | pathogenic | Developmental and epileptic encephalopathy, 2; Angelman syndrome-like | 2019-04-12 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exons 2-12 of the CDKL5 gene, which includes the initiator codon. 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 12 of the CDKL5 gene. This is expected to result in an absent or disrupted protein product. Isolated deletions of exons 2-12 of CDKL5 have not been reported in the literature. However, copy number events that include the initiator codon have been reported (PMID:21293276, 19471977, 20848651). Loss-of-function variants in CDKL5 are known to be pathogenic (PMID: 22872100). For these reasons, this variant has been classified as Pathogenic. |
