Invitae | RCV001299564 | SCV001488660 | uncertain significance | Developmental and epileptic encephalopathy, 2; Angelman syndrome-like | 2020-08-17 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CDKL5 protein function. This variant has not been reported in the literature in individuals with CDKL5-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with leucine at codon 446 of the CDKL5 protein (p.Ser446Leu). The serine residue is highly conserved and there is a large physicochemical difference between serine and leucine. |
