30
Q

GINA

A
  • Genetic information non-discrimination act of 2008
  • Prohibits discrimination in health coverage/employment based on genetic info
31
Q

Autosomal dominant

A
  • Mutation of a single gene pair
  • Heterozygous
  • 1 copy of mutated gene needed to get disorder
32
Q

Example of autosomal dominant disorders

A

  • Huntington’s Disease
  • Neurofibromatosis
33
Q

Autosomal recessive

A
  • Mutation in 2 gene pairs
  • Homozygous
  • Need 2 copies of mutation to get disorder
34
Q

A
  • CF
  • Sickle cell
  • Tay-sach’s disease
35
Q

X-linked recessive

A
  • Mutation of 1 or 2 gene pairs with 1 mutated gene on the x chromosome
36
Q

Examples of x-link recessive disorders

A
  • Hemophilia
  • Duchenne muscular dystrophy
37
Q

X linked dominant

A

Dominant gene is carried on the X chromosome and only 1 allele is needed to get the disorder

38
Q

CF patio in lungs

A
  • GERD
  • Gallstones
  • Pancreatitis
  • Constipation

Mucous plugs duct and impairing flow of bile and pancreatic enzymes

41
Q

Pancreatic atrophy leads to

A

CF related diabetes

42
Q

Maldigestion

A

Insufficient production of lipase, amylase, protease causes poor absorption of nutrients
