Rett and Angelman-like Disorders VCEP

The allele frequency of the p.Ile508Thr variant in CDKL5 is 0.018% in European (Non-Finnish) sub population in gnomAD, which is high enough to be classified as likely benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BS1). The p.Ile508Thr variant is observed in at least 2 unaffected individuals (internal database) (BS2). Computational analysis prediction tools suggest that the p.Ile508Thr variant does not have a deleterious impact; however this information does not predict clinical significance on its own (BP4). In summary, the p.Ile508Thr variant in CDKL5 is classified as benign based on the ACMG/AMP criteria (BS1, BS2, BP4).
