Low doses of paraquat and polyphenols prolong life span and locomotor activity in knock-down parkin Drosophila melanogaster exposed to oxidative stress stimuli: implication in autosomal recessive juvenile parkinsonism.
In addition, haplotype analysis should be employed to check for homozygosity of 1p36, which harbors a cluster of causative genes for ARP such as DJ-1, PINK1 and ATP13A2 in ARP and sporadic parkinsonism, especially in parkinsonism with consanguinity.
Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene have been identified as a much more common cause for dominant PS, especially in certain ethnic groups, while mutations in the parkin gene, in DJ-1, PINK1 and ATP13A2 cause autosomal recessive parkinsonism of early onset.
