Similar results were observed for Val380Leu (G>C) and IVS4 + 30T>G polymorphisms which suggest their role in element concentration and neurological symptoms.
DJ-1/PARK7, But Not Its L166P Mutant Linked to Autosomal Recessive Parkinsonism, Modulates the Transcriptional Activity of the Orphan Nuclear Receptor Nurr1 In Vitro and In Vivo.
The clinical phenotype comprised of asymmetrical onset, slowly progressive Parkinsonism with levodopa induced motor restlessness in a patient with the novel mutation (c.313 A > T, p. Ile105Phe) while subjects with c.293 G > A, p.Arg98Gln had early onset levodopa responsive symmetrical Parkinsonism.

Two novel DJ-1 mutations, c.91-2A>G affecting splicing and c.319G>C causing Ala107Pro, were observed among patients with AAO of <31 years, suggesting that PD in a high fraction (>12%) of this group of Iranian patients may be due to mutations in DJ-1.Mutations in PINK1 were not observed.
The deleterious effect of each Parkinsonism-associated mutation on DJ-1 is dissected by analysis of engineered substitutions (M26L, A104V, and E163K/R145E) that partially alleviate each of the defects introduced by the A104T, E163K and M26I mutations.
In this study we show that three different Parkinsonism-associated DJ-1 missense mutations (A104T, E163K, and M26I) reduce the thermal stability of DJ-1 in solution by subtly perturbing the structure of DJ-1 without causing major folding defects or loss of dimerization.
To further investigate whether pathogenic mutations might prevent the distribution of DJ-1 to mitochondria, we generated human neuroblastoma cells stably transfected with wild-type (WT) or mutant (M26I, L166P, A104T, D149A) DJ-1 and performed mitochondrial fractionation and confocal co-localization imaging studies.

Both homozygous (L166P, M26I, deletion) and heterozygous mutations (D149A, A104T) in the DJ-1 gene have been identified in Parkinson's disease (PD) patients.
