RCV003235178 | SCV003933695 | likely pathogenic | CDKL5 disorder | 2023-04-14 | reviewed by expert panel | curation | The p.Arg717= variant in CDKL5 occurs in the de novo state (biological parentage confirmed) in an individual (Invitae internal database )(PS2). The p.Arg717= variant in CDKL5 occurs in the de novo state (biological parentage unconfirmed) in an individual (GeneDx internal database). The p.Arg717= variant has been observed in at least 2 individuals with neurological disease (Invitae and GeneDx internal database). The p.Arg717= variant in CDKL5 is absent from gnomAD (PM2_supporting). In summary, the p.Arg717= variant in CDKL5 is classified as likely pathogenic for a CDKL5-related disorder based on the ACMG/AMP criteria (PS2, PS4_supporting, PM2_supporting). |

Invitae | RCV001379966 | SCV001577882 | likely pathogenic | Developmental and epileptic encephalopathy, 2; Angelman syndrome-like | 2023-10-03 | criteria provided, single submitter | clinical testing | This sequence change affects codon 717 of the CDKL5 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the CDKL5 protein. It affects a nucleotide within the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with clinical features of CDKL5-related conditions (Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 286706). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
