A study by researchers at the Institute for Neurological Disease, Massachusetts General Hospital, Boston has found four new genes that they think are implicated in the development of Alzheimer's disease. The researchers tested samples from more than 400 families in which at least three members had Alzheimer's disease. The analysis revealed five genetic markers linked to Alzheimer's. One was a gene called APOE which was already known about but the researchers also found other markers on chromosome 14; in a gene known to cause a movement disorder called spinocerebellar ataxia, in a gene involved in the immune system and in a gene that produces proteins in synapses.
