  1. Huntington’s disease (Huntington’s Chorea) (Chorea) (HD) By: Alex Taylor

  2. Inheritance Patterns • Autosomal Dominant • Which means the gene involved is one that comes through a cell created by mitosis not meiosis. • It is a dominant allele • Recently localized upon the fourth chromosome • It dominates the other genes, and causes them to lose their functionality, causing issues in later life.

  3. Other Information • Not in a gamete, so it affects both sexes equally, giving 50% chance for an infected father and a healthy mother to have infected children of either sex. • It is a neurological disorder, so it causes involuntary movements and loss of motor control also, personality changes may occur, with loss of memory and decreased mental capacity. • Typically noticed by shudders, going through the body involuntarily during the third or fourth decade of life, although the age of discovery and symptoms changes by person. • Pretty uncommon, with the disorder showing up every 3-7/100000 people of European descent. It is very rare, and with even less cases showing in Japanese and African Americans. • Although it causes some inconveniences and shudders, it is not deadly.
