By contrast, in familial cases of parkinsonism without Lewy bodies, such as in PARK2, the autonomic profile remains normal throughout the course of the disease.
Mutations in the GCH1 gene are the most common cause of DRD, however, in some cases when the disease is associated with parkinsonism mutations in the PARK2 gene may be identified.

PARK2 (PARKIN) is an E3 ubiquitin ligase whose dysfunction has been associated with the progression of Parkinsonism and human malignancies, and its role in cancer remains to be explored.
Mutations in the PARK2 and PARK6 genes, coding for the cytosolic E3 ubiquitin protein ligase Parkin and the mitochondrial serine/threonine kinase PINK1 [phosphatase and tensin homologue (PTEN)-induced putative kinase 1], lead to clinically similar early-onset Parkinsonian syndromes.
PINK1 (PTEN induced putative kinase 1) and PARKIN (also known as PARK2) have been identified as the causal genes responsible for hereditary recessive early-onset Parkinsonism.
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 three forms, caused by mutations in parkin (PARK2), PINK1 (PARK6), or DJ-1 (PARK7), the phenotype is usually characterized by levodopa-responsive parkinsonism without atypical features.
We cover dopa-responsive dystonia, Wilson's disease, Parkin-, PINK1-, and DJ-1-associated parkinsonism (PARK2, 6, and 7), x-linked dystonia-parkinsonism/Lubag (DYT3), rapid-onset dystonia-parkinsonism (DYT12) and DYT16 dystonia, the syndromes of Neurodegeneration with Brain Iron Accumulation (NBIA) including pantothenate kinase (PANK2)- and PLA2G6 (PARK14)-associated neurodegeneration, neuroferritinopathy, Kufor-Rakeb disease (PARK9) and the recently described SENDA syndrome; FBXO7-associated neurodegeneration (PARK15), autosomal-recessive spastic paraplegia with a thin corpus callosum (SPG11), and dystonia parkinsonism due to mutations in the SLC6A3 gene encoding the dopamine transporter.
Although mutations in the parkin gene are frequently associated with familial Parkinsonism, emerging evidence suggests that parkin also plays a role in cancers as a putative tumor suppressor.
