Abstract:
PURPOSE: A composition for early diagnosing Alzheimer's disease is provided to easily diagnose dementia based on C methylation ratio in CpG. CONSTITUTION: A composition for early diagnosing Alzheimer's disease contains a formulation which measures methylation level of PEG1(paternally expressed gene 1) promoter. A method for early diagnosing Alzheimer's disease comprises: a step of treating bisulfite to genome DNA isolated from blood; a step of performing PCR of the genome DNA using a PEG1 promoter-specific primer; a step of determining methylation ratio of C in CpG; and a step of diagnosing dementia when the C methylation level is higher than a healthy person.
