Transcripts expressed by CCDC92, GRIA4, HDAC7, and IFITM3 were reported to be significantly DE in AD blood transcriptome, as well as documented to be involved in other neurological disorders or pathways contributing to AD pathology, such as immunity (Gupta et al. 2020; Hur et al. 2020; Abdullah et al. 2022). This evidence concerns the gene HDAC7 and Alzheimer disease.
