Adult onset neurodegenerative disorder
Gene: SGCE
Onset of the disorder is usually in the first or second decade. Myoclonic dystonia, or myoclonus-dystonia, has dystonia as the core feature, but tremor or rapid jerky movements resembling myoclonus may also be present. Not sure if it can be classified as neurodegenerative.Created: 2 Sep 2019, 4:06 p.m. | Last Modified: 2 Sep 2019, 4:06 p.m.
Panel Version: 1.99
Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, maternally imprinted (paternal allele expressed)
Phenotypes
Myoclonus dystonia syndrome; Myoclonus-Dystonia; maternally imprinted Dystonia-11, myoclonic, 159900
Meta-analysis found that Myoclonic dystonia associated with psychiatric disorders including depression, anxiety and alcohol abuse (23332219). Other studies have suggested that cognitive deficits, specifically
executive impairments, may be part of the clinical spectrum (22626943).Created: 23 Jul 2019, 3:35 p.m. | Last Modified: 23 Jul 2019, 3:35 p.m.
