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.

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.
