Methods of identifying genetic risk for and evaluating treatment of alzheimer's disease by determining cyp46 genotype

摘要

Based on the unexpected identification of a CYP46 gene polymorphism as a novel genetic risk factor that links cholesterol metabolism to Alzheimer's disease, the present invention provides a method of diagnosing or prognosticating Alzheimer's disease, or determining the propensity or predisposition of a subject to develop Alzheimer's disease. The method comprises detecting the presence or absence of a variation in the CYP46 gene which encodes the enzyme cholesterol 24-hydroxylase.
