Mechanism for neurodenegerative diseases linked to transport proteins

...sually between the ages of 30 and 50. Huntington's strikes about four times as many. Neurodegenerative diseases like SBMA are caused by the lengthening of part of a gene that encodes repetitions of the amino acid glutamine in the protein. Although different genes are affected, all of the polyglutamine-expan...
