An expansion of a trinucleotide CAG repeat on chromosome 4 causes Huntington disease. The abnormal elongation of the CAG increases the polyglutamine stretch of huntingtin, which becomes proportionally toxic. The mutated huntingtin is ubiquitous in somatic tissues, yet the pathologic changes are apparently restricted to the brain. The degree of the abnormal(More)
The accumulation of fibrillar α-synuclein protein is the pathological hallmark occurring in both multiple system atrophy (MSA) and diffuse Lewy body disease (DLBD). The oligodendrocytes are especially involved in MSA, while subtypes of neurons are the targets in DLBD. In both instances, the changes are widespread within the central nervous system, but with(More)
