Criteria Specifications for this VCEP
Evidence submitted by expert panel
Rett and Angelman-like Disorders VCEP
The p.Tyr941fs variant in CDKL5 is predicted to cause a premature stop codon that leads to a truncated or absent protein in a gene where loss-of-function is an established mechanism. There is significant evidence that loss of this region of the gene is pathogenic (PVS1). The p.Tyr941fs variant in CDKL5 has been reported as a de novo occurrence (biological parentage confirmed) in an individual with CDKL5 disorder (internal database) (PS2). The p.Tyr941fs variant in CDKL5 is absent from gnomAD (PM2_Supporting). In summary, the p.Tyr941fs variant in CDKL5 is classified as pathogenic for CDKL5 disorder based on the ACMG/AMP criteria (PVS1, PS2, PM2_Supporting).
