The relationships of the aldehyde dehydrogenase 1 family member A2 (ALDH1A2), DIO2 antisense RNA 1 (DIO2-AS1), JH3, potassium calcium-activated channel subfamily N member 3 (KCNN3), long noncoding RNAs bladder and prostate cancer suppressor (LNC-LBCS), RNA binding motif single stranded interacting protein 3 (RBMS3) and RNA, U6 small nuclear 909, and pseudogene (RNU6-909P) genes, and AD, IS were only observed in populational studies and have not been confirmed in molecular studies yet. Here, ALDH1A2 is linked to Alzheimer disease.
