People with a gene called ApoE-4 are three to eight times as likely to develop Alzheimer's disease. Researchers from the University of California, Irvine have now found another gene that they believe is linked to the condition. The researchers found that a harmful form of the gene TOMM40 appears twice as often in people with Alzheimer's disease as in people without the condition. Having the harmful form of TOMM40 and ApoE-4 significantly increased people's susceptibility to Alzheimer's.
