Cardiac phenotype in ATP1A3-related syndromes
Balestrini, Simona; Mikati, Mohamad A.; Álvarez-García-Rovés, Reyes; Carboni, Michael; Hunanyan, Arsen S.; Kherallah, Bassil; McLean, MelissaObjective: To define the risks and consequences of cardiac abnormalities in ATP1A3-related syndromes. Methods: Patients meeting clinical diagnostic criteria for rapid-onset dystonia-parkinsonism (RDP), alternating hemiplegia of childhood (AHC), and cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss (CAPOS) with ATP1A3 genetic analysis and at least 1 cardiac assessment were in...
Delineating the GRIN1 phenotypic spectrum: a distinct genetic NMDA receptor enc...
Lemke, Johannes R.; Geider, Kirsten; Helbig, Katherine L.; Heyne, Henrike O.; Schutz, Hannah; Hentschel, Julia; Courage, Carolina; Depienne, ChristelObjective:To determine the phenotypic spectrum caused by mutations in GRIN1 encoding the NMDA receptor subunit GluN1 and to investigate their underlying functional pathophysiology.Methods:We collected molecular and clinical data from several diagnostic and research cohorts. Functional consequences of GRIN1 mutations were investigated in Xenopus laevis oocytes.Results:We identified heterozygous de novo GRIN1 mut...
