The IPA network identified ATXN3 and FBXW7 in the same disease pathway as PARK2 (Parkin); CHCHD3 and KLC1 as SNCA; AATF, HSF1, and KLC1 as MAPT; TCF3 and MBD3 as DJ-1 (PARK7); TUBB4B and NSF as LRRK2. We also examined differential expression of the candidate genic CNVs that we identified using published PD microarray datasets and the National Center for Adult Stem Cell Research Parkinson's Review database (http://ncascr.griffith.edu.au/pdreview/2009/) (Sutherland et al. 2009). Here, HSF1 is linked to Parkinson disease.
