Invitae | RCV001247902 | SCV001421354 | pathogenic | Developmental and epileptic encephalopathy, 9 | 2022-05-11 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 566 of the PCDH19 protein (p.Pro566Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of developmental and epileptic encephalopathy (Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 971984). 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 expected to disrupt PCDH19 protein function. For these reasons, this variant has been classified as Pathogenic. |
