Epileptic Encephalopathy Due to BRAT1 Pathogenic Variants
Investigators from Institut für Medizinische Genetik und Humangenetik have highlighted the role of compound heterozygous BRAT1 variants in two German brothers with variable presentations of intractable epilepsy, poor development, postnatal microcephaly, hypertonia, apnea, and infantile/childhood death.
متن کاملProduction of transmitochondrial cybrids containing naturally occurring pathogenic mtDNA variants
The human mitochondrial genome (mtDNA) encodes polypeptides that are critical for coupling oxidative phosphorylation. Our detailed understanding of the molecular processes that mediate mitochondrial gene expression and the structure-function relationships of the OXPHOS components could be greatly improved if we were able to transfect mitochondria and manipulate mtDNA in vivo. Increasing our kno...
متن کاملResponse to immunotherapy in a patient with adult onset Leigh syndrome and T9176C mtDNA mutation
Leigh syndrome is a mitochondrial disease caused by mutations in different genes, including ATP6A for which no known therapy is available. We report a case of adult-onset Leigh syndrome with response to immunotherapy. A twenty year-old woman with baseline learning difficulties was admitted with progressive behavioral changes, diplopia, headaches, bladder incontinence, and incoordination. Brain ...
متن کاملWhy does Leigh syndrome respond to immunotherapy?
With interest we read the article by Chuquilin et al. about a 20yo femalewith Leigh syndromedue to them.9176T N Cmutation in the ATP6 gene who responded favourably to plasmapheresis and immunoglobulins [1]. We have the following comments and concerns. Themain ambiguity of this report is thediagnosis. Except for the current case, Leigh syndrome has not been reported to respond to immunosuppressi...
متن کاملDefective complex I assembly due to C20orf7 mutations as a new cause of Leigh syndrome
BACKGROUND Leigh syndrome is an early onset, progressive, neurodegenerative disorder with developmental and motor skills regression. Characteristic magnetic resonance imaging abnormalities consist of focal bilateral lesions in the basal ganglia and/or the brainstem. The main cause is a deficiency in oxidative phosphorylation due to mutations in an mtDNA or nuclear oxidative phosphorylation gene...
