The risk of Parkinson’s is increased if you have a mutation in a gene called GBA, which codes for one of the digestive enzymes involved in autophagy. Parkinson’s is accompanied by ‘Lewy bodies’, clumps of a protein called alpha-synuclein that are toxic to brain cells. The problematic, sticky form of alpha-synuclein is normally degraded by autophagy, but even a small impairment caused by a minor GBA mutation is enough to slow its breakdown, increase its levels and thus increase the risk of getting Parkinson’s. Impaired autophagy is also associated with Alzheimer’s and Huntington’s disease, arthritis and heart problems.
