View source for Chromosome 14 - Alzheimer Disease

[[Biology]] 
Chromosome 14 contains the maker for Alzheimer disease.  
Alzheimer disease is the fourth leading cause of death in adults, and the likelihood of getting it increases with age.
Observed symptoms: progressive inability to remember facts and events and, later, to recognize friends and family.
Mutation on chromosomes 1, 14, 19, and 21 are believed to play a role.  Alzheimer runs in the family.  A mutation is PS1 (or AD3) on chromosome 14.
Fragments brain around amyloid-family proteins – somewhat similar to Down Syndrome
Research in mice identified an enzyme that may be responsible for the increase in amyloid production characteristic of AD. If a way to regulate this enzyme could be found, then AD may be slowed or halted in some people.
