Invitae RCV001244788 SCV001418032 pathogenic Early infantile epileptic encephalopathy 2; Angelman syndrome-like 2019-10-16 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg550*) in the CDKL5 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in several individuals affected with CDKL5-related conditions (PMID: 18063413, 21318334, 22678952). ClinVar contains an entry for this variant (Variation ID: 143780). Loss-of-function variants in CDKL5 are known to be pathogenic (PMID: 22872100). For these reasons, this variant has been classified as Pathogenic.
