Invitae RCV000694251 SCV000822686 pathogenic Early infantile epileptic encephalopathy 2; Angelman syndrome-like 2018-07-03 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg559*) 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 individuals with epilepsy (PMID: 27770071, 27823948, 22872100) and to be de novo in an individual affected with suspected early onset encephalopathy (PMID: 19161156). ClinVar contains an entry for this variant (Variation ID: 143781). Loss-of-function variants in CDKL5 are known to be pathogenic (PMID: 22872100). For these reasons, this variant has been classified as Pathogenic.
