Is alzheimers disease a autosomal recessive trait?
The early-onset form of the disease is autosomal dominant. A rare form of the disease, Familial Autosomal Dominant Alzheimer’s Disease (FAD), accounts for approximately five to 10 per cent of all cases. It is known to be inherited — the disease will occur if the disease gene is present. In certain families, FAD is passed directly from one generation to another through a dominant inheritance pattern. This means that if a parent is affected, each child has a 50 per cent chance of inheriting the disease gene and will develop Alzheimer’s disease in adulthood.
