Mutations in NKX6-2 Cause Progressive Spastic Ataxia and Hypomyelination
Progressive limb spasticity and cerebellar ataxia are frequently found together in clinical practice and form a heterogeneous group of degenerative disorders that are classified either as pure spastic ataxia or as complex spastic ataxia with additional neurological signs. Inheritance is either autosomal dominant or autosomal recessive. Hypomyelinating features on MRI are sometimes seen with spa...
متن کاملChildhood ataxia with cerebral hypomyelination (CACH) syndrome: a study of three siblings.
We report a family of three siblings with Childhood Ataxia with Cerebral Hypomyelination. All the siblings presented with early onset cerebellar ataxia beginning around five years of age with mild mental retardation. MRI showed diffuse white matter signal changes in all three patients with cerebellar atrophy while the spectroscopy was abnormal only in the eldest who was the most severely affect...
متن کاملMutations causing childhood ataxia with central nervous system hypomyelination reduce eukaryotic initiation factor 2B complex formation and activity.
Childhood ataxia with central nervous system hypomyelination (CACH), or vanishing white matter leukoencephalopathy (VWM), is a fatal brain disorder caused by mutations in eukaryotic initiation factor 2B (eIF2B). eIF2B is essential for protein synthesis and regulates translation in response to cellular stresses. We performed mutagenesis to introduce changes equivalent to 12 human CACH/VWM mutati...
متن کاملAGC1 deficiency associated with global cerebral hypomyelination.
The mitochondrial aspartate-glutamate carrier isoform 1 (AGC1), specific to neurons and muscle, supplies aspartate to the cytosol and, as a component of the malate-aspartate shuttle, enables mitochondrial oxidation of cytosolic NADH, thought to be important in providing energy for neurons in the central nervous system. We describe AGC1 deficiency, a novel syndrome characterized by arrested psyc...
متن کاملNeurochemistry of Hypomyelination Investigated with MR Spectroscopy.
Proton magnetic resonance spectroscopy (MRS) allows the noninvasive exploration of tissue metabolism in vivo, providing neurophysiological and neurochemical information. N-acetylaspartate (NAA) is generally considered to be a marker of neurons and axons, and many neurodegenerative disorders, including demyelinating disorders, exhibit a decrease in total NAA (tNAA). MRS in human hypomyelination ...
