The affected genes included the nucleosome stability histone H2A, BCL2 which is involved in striatal neurons and considered to be a compensatory mechanism in PD [95], MLLT10 involved in lymphoblastic lymphoma [96], Chorod1 involved in brain development [97], the potential neuro-protector PON2 [98] and the iron homeostasis involved gene FBXL5 [99]. This evidence concerns the gene PON2 and Parkinson disease.
