Transcript levels of the anti-oxidant NQO1 were significantly elevated in Gaucher disease [0.017 (IQR 0.014–0.019), Mann-Whitney U-test P = 0.012] and Parkinson’s disease with GBA mutation fibroblasts [0.02 (0.016–0.023), P = 0.024] compared with controls [0.01 (IQR 0.007–0.014)]. This evidence concerns the gene GBA1 and Parkinson disease.
