Genetics and Parkinson's disease.
Idiopathic Parkinson's disease is a neurodegenerative disorder that affects 1-2% of the population over the age of 65 years. Its aetiology is most likely a combination of complex genetic and environmental factors. Although Mendelian inheritance is seen in less than 5% of cases, recent studies have identified three genes mutations causing Parkinson's disease with a Mendelian inheritance pattern: autosomal dominantly inherited mutations of the alpha-synuclein gene on chromosome 4q21-q23, autosomal recessively inherited mutations of the parkin gene on chromosome 6q25.2-q27 and an autosomal dominantly inherited mutation of the Ubiquitin C-terminal hydrolase L1 (UCH-L1) gene on chromosome 4p14-15.1. A number of other candidate gene polymorphisms including cytochrome P450 2D6, N-acetyltransferase 2, monoamine oxidase-B and glutathione-s-transferase M1 are implicated in sporadic and familial cases and may also play a minor role in the aetiology of Parkinson's disease.
