While there is no cure or definitive cause of Alzheimer’s disease, researchers have been focusing on genetic links which may contribute to this disease. Researchers have found one particular gene which they believe to be a risk factor for developing late-onset Alzheimer’s disease in those who inherit it. genee
This gene is the “APOE gene” or “apolipoprotein E gene” of which there are three types called “alleles” that are the most commonly found: “APOE e2, APOE e3, and APOE e4.” It is the “APOE e4” gene that researchers have determined to be the gene which increases the risk for Alzheimer’s.
One APOE allele is inherited from each biological parent and if an individual inherits one or two of the APOE e4 gene they are at a greater risk for developing Alzheimer’s disease however, this does not mean that the individual will acquire the disease for certain.
People who inherit two of the APOE e4 are at a greater risk however, some of these individuals never show symptoms while others who do not even have this particular gene at all develop Alzheimer’s. Therefore the level of risk for an individual who is carrying the APOE e4 gene can not be determined which is why these genes are only considered as risk factors.
APOE Research and Testing
While blood testing is done for the APOE genes, even if an individual has the APOE e4 gene this cannot determine whether or not they will acquire Alzheimer’s disease however, this testing can be useful for researchers as they can then do further testing by looking for any characteristics of Alzheimer’s in the brain of individuals with the APOE e4 gene.
This testing is generally not used in the diagnosis of Alzheimer’s disease however, in some cases where a medical evaluation has determined that an individual most likely has this disease; this test may be used in combination with other medical testing to solidify the stylowakobieta
