In line with the two previous reports [28, 34], our study provides further evidence that neither the LIMP2 level nor GCase activity are affected by the genotype at rs681193 or rs6825004 locus in PD fibroblast cells, and hence, does not explain the reduction of LIMP2 observed at the transcript and protein level in idiopathic PD group of cells compared to age matched controls. Here, SCARB2 is linked to Parkinson disease.
