The most common gene associated with late-onset Alzheimer's disease is called apolipoprotein E (APOE). APOE has three common forms: 1  APOE e2 â the least common â appears to reduce the risk of Alzheimer's. 2  APOE e4 â a little more common â appears to increase the risk of Alzheimer's.
Human chromosomes. Chromosomes in humans can be divided into two types: autosomes (body chromosome(s)) and allosome (sex chromosome(s)). Certain genetic traits are linked to a person's sex and are passed on through the sex chromosomes. The autosomes contain the rest of the genetic hereditary information. All act in the same way during cell division. Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell.
