Regression
Gene: AARS2
6 reported with a progressive neurodegenerative disorder characterised by loss of motor and cognitive skills, usually with onset in young adulthood. Some had a history of delayed motor development or learning difficulties in early childhood. Neurologic decline was severe, usually resulting in gait difficulties, ataxia, spasticity, and cognitive decline and dementia. Most individuals lost speech and become wheelchair-bound or bedridden. Brain MRI showed progressive white matter signal abnormalities in the deep white matter. Affected females developed premature ovarian failure. Please note at least 6 families presenting with a severe COXPD phenotype in infancy, primarily with cardiac, muscle and neurological features in addition to lactic acidosis also reported. These likely represent a spectrum of severity of a single mitochondrial disorder.Created: 29 Aug 2020, 5:03 a.m. | Last Modified: 29 Aug 2020, 5:03 a.m.
