Metafeatures in this cluster contained probe sets for three genes previously investigated in the context of AD (CYP3A4[74], [75], [76], ATP2B2[77], [78] and PPP2CA) and four other genes previously highlighted by the analysis of Gomez Ravetti et al. [5] (PTEN, PRKCB1, FCAR and CPT2). Here, PPP2CA is linked to Alzheimer disease.
