Researchers reviewed the novel mutations found in genes associated with early-onset Alzheimer’s disease in Asian countries, arguing that identifying disease-associated mutations greatly contributes to the knowledge of the cause and effect of the disease. This information is also essential to develop preventive and therapeutic strategies. The study, “Mutations, Associated With Early-Onset Alzheimer’s Disease, Discovered In Asian Countries,” was published in the journal of Clinical Interventions in Aging. Alzheimer’s disease can be classified into the early-onset and late-onset types. The early-onset form is more rare and hereditary, developing before the age of 65. Essentially, three genes are known to be involved in this form of the disease: APP, PSEN1, and PSEN2. APP encodes the amyloid precursor protein which, when cleaved, will become the beta-amyloid protein, whose toxic accumulation is the hallmark of Alzheimer’s. The other two genes, PSEN1 and PSEN2, encode proteins that cleave the amyloid precursor protein, contributing to the formation of the beta-amyloid protein. Mutations in these three genes may promote beta-amyloid production and accumulation. Here, researchers reviewed all of the known mutations in these three genes that were discovered in Asian countries, such as Japan, Korea, and China. According to the authors, 30 novel Asian mutations were found in APP, PSEN1, and PSEN2 comparing Caucasian and Asian patients.
