Late-onset genes for Alzheimer's disease
Professor Donna Wilcock discusses the late-onset gene for Alzheimer's disease, ApoE4, which increases the risk of developing the disease.
There is one, right now, genetic risk factor for Alzheimerâ€™s disease thatâ€™s called ApoE. ApoE is a complicated molecule that seems to be involved in cholesterol transport, but it probably has many other functions as well as cholesterol transport. Everybody in the general population has two copies of the ApoE gene, and you can be ApoE2, ApoE3, or ApoE4. You have two copies â€“ you get one copy from your mom and one copy from you dad. You can be an ApoE2/ApoE3, or you can two ApoE3s, or you can have ApoE3/ApoE4. If you carry one ApoE4 gene, you have a slightly increased risk of Alzheimerâ€™s disease. If you have two copies of the ApoE4 gene, you have a much higher risk of developing Alzheimerâ€™s disease. This is the first susceptibility gene that weâ€™ve found for late-onset Alzheimerâ€™s disease but it is not a definite gene. You can have ApoE4/ApoE4 and not go on to develop Alzheimerâ€™s disease. But you are at a much higher risk of to have Alzheimerâ€™s disease than letâ€™s say an ApoE3/ApoE3 is.
