SOX6 and Parkinson disease: So we assessed PD array databases, initially looking at the genes defining dopaminergic neuron development and phenotype (such as FOXA2, LMX1A, EN1, EN2, SLC18A2, TH, DDC, ALDH1A1, NR4A2, PITX3, SOX6) as well as more generic markers of a neuronal phenotype (SNCA, SYP, FABP7, GCH1, PTS, TUBB3, MAP2).
