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...
Undetectable Levels of CSF Amyloid-β Peptide in a Patient with 17β-Hydroxystero...
Ortez, C; Villar, C; Fons, C; Duarte, ST; Pérez, A; García-Villoria, J; Ribes, A; Ormazábal, A; Casado, M; Campistol, Jaume; Vilaseca, MA17β-hydroxysteroid dehydrogenase 10 (HSD10) deficiency is a rare X-linked inborn error of isoleucine catabolism. Although this protein has been genetically implicated in Alzheimer's disease pathogenesis, studies of amyloid-β peptide (Aβ) in patients with HSD10 deficiency have not been previously reported. We found, in a severely affected child with HSD10 deficiency, undetectable levels of Aβ in the cerebrospina...
