Here we identify USP24 (ubiquitin specific peptidase 24), a gene located in the PARK10 (Parkinson disease 10 [susceptibility]) locus associated with late onset PD, as a novel negative regulator of autophagy.
The rs10788972 variant of the transcription elongation factor A (SII) N-terminal and central domain containing 2 (TCEANC2) gene in the PARK10 region was recently identified to be strongly related to sporadic PD in the American population.
However, additional studies are needed to assess the role of PARK10 in modifying age at onset and to determine whether rare variants in this region might affect PD susceptibility.
A validated family history of Parkinson disease questionnaire was administered to 119 patients with Gaucher disease who were evaluated at the Mount Sinai School of Medicine from 2009 to 2012; the ages of their parents, siblings, and children, history of Parkinson disease, age at onset ofParkinson disease, and ethnic background were obtained.
Herein, we investigate whether single-nucleotide polymorphisms (SNPs) across the PARK10 locus are associated with susceptibility to Parkinson's disease (PD) or age at onset (AAO) of disease.
Genetic variability in ELAVL4 located in the PARK10 locus was recently associated with age-at-onset (AAO) in a series of Parkinson's disease (PD) patients originating from the United States.
Collectively, these findings identify RNF11 as a strong candidate gene at the PARK10 locus and highlight its potential significance in the development of the common form of PD.
The known or putative functions of these genes fit well with the current suspected pathogenic mechanisms of PD and thus show great potential as candidates for the PARK10 locus.
In analysis of the combined tier 1 and tier 2b data, the two SNPs with the lowest P values (P=9.07 x 10(-6); P=2.96 x 10(-5)) tagged the PARK10 late-onset PD susceptibility locus.
