Extended mutation analysis and association studies of Nurr1 ( NR4A2 ) in Parkinson disease

Abstract
The transcription factor Nurr1 is highly expressed in dopaminergic cells of the substantia nigra. Deficiency of Nurr1 in mice leads to a lack of dopaminergic neurons.4 Based on these data, we explored the 7048G7049 polymorphism in intron 6 as well as two novel sequence variations, −291Tdel and −245T→G, in exon 1 of Nurr1 in a large cohort of PD patients.
