Exceptions were CERS5 (lower levels in cerebellum of AD cases; not significant in the meta-analysis), CERS6 (higher levels in cerebellum vs. lower levels in the parahippocampal gyrus of AD cases; not significant in the meta-analysis), and SMPD3 (lower levels in the temporal cortex of AD cases; also significant in the meta-analysis). The gene discussed is CERS6; the disease is Alzheimer disease.
