Researchers make headway toward understanding Alexander disease
Using a mouse model for this disease, researchers at the University of Wisconsin-Madison have found that a protein behind the symptoms of Alexander disease, called GFAP, is broken down more rapidly in the body than researchers previously found in cell culture studies.

Metformin as a potential treatment for maple syrup urine disease
Publishing in Scientific Reports, researchers show that the widely-used diabetes drug metformin reduces the toxic acid levels associated with maple syrup urine disease in both skin cells derived from maple syrup urine disease patients and in mice. The discovery offers the possibility of a new treatment.

Highly efficient agent against Wilson disease
In the Journal of Clinical Investigation, scientists describe a small peptide that very efficiently binds excess copper from liver cells. This molecule comes from a bacterium's bag of tricks and could be suitable for treating Wilson disease. In an experimental model it has already proven superior to conventional medicines.

Stem-cell model for Smith-Lemli-Opitz syndrome
Studies performed by a Sanford Research scientist uncovered unique cellular defects associated with Smith-Lemli-Opitz syndrome by modeling this disease using induced pluripotent stem cells. It was discovered that 7DHC accumulation, not cholesterol deficiency, was a hallmark of these cells.

New syndrome named, causes a rare intellectual disability
Pediatric researchers, using high-speed DNA sequencing tools, have identified a new syndrome that causes intellectual disability, hypotonia, and seizures. Drawing on knowledge of the causative gene mutation - TBCK, the scientists' cell studies suggest that an amino acid supplement - leucine - may offer a targeted treatment for children with this condition.

First human in vitro model of Cockayne syndrome created
This work, published in the current online issue of the journal Human Molecular Genetics, provides an alternative to existing models for studying neural-specific aspects of Cockayne syndrome. It reveals that the CSB protein is required for normal neuronal function, and shows the feasibility of constructing a new and relevant human in vitro model with potential clinical interest.

Loss of cellular energy leads to neuronal dysfunction in neurodegenerative disease model
A new study from the Gladstone Institutes that used a model of Leigh disease shows for the first time that impairments in mitochondria can deplete cellular energy levels and cause neuronal dysfunction in a model of neurodegenerative disease.

Breakthrough in understanding Canavan disease
Through a series of elegant experiments, researchers at UC Davis have uncovered the biochemical underpinnings of Canavan disease. The team identified an abnormally high buildup of the second most common molecule in the brain, N-acetylaspartate (NAA), as the culprit that causes the syndrome's destructive effect.
