Six transcripts (MRPL51, NDUFA1, NDUFS5, two Illumina probes for RPL36AL, and LOC646200 (similar to 60S ribosomal protein L22, heparin-binding protein HBp15, NCBI record removed) were selected in both training sessions of random forest analysis on the AD blood datasets. This evidence concerns the gene NDUFS5 and Alzheimer disease.
