RFX5 and Alzheimer disease: We identified three non-coding RNAs significantly associated with AD (AC007278.2, AC007248.7, and RP11-85K15.2) and four novel AD genetic risk genes, leucine rich repeat and Ig domain containing 4 (LINGO4), regulatory factor X5 (RFX5), prolyl-4 hydroxylase subunit alpha 2 (P4HA2), and RNA binding motif protein 17 (RBM17), which were not identified in previous GWAS studies.
