Study Notes

Objectives

  • Discuss family history as a predictor of disease risk.
  • Identify appropriate uses for DNA testing, and explain how such tests might lead to genetic discrimination.
  • Define genetic engineering, and explain why cloning and stem cell research are controversial issues.
  • Explain three possible remedies for couples experiencing infertility problems.
  • List those laws affecting healthcare that pertain especially to children's rights.

Vocabulary

  • Heredity: The process by which genetic traits are passed on to offspring.
  • Genetics: The science that accounts for differences and resemblances among people and other organisms related by descent.
  • DNA (deoxyribonucleic acid): Makes up chromosomes.
  • Gene: A segment of DNA that contains the formula for building a protein.

DNA

  • The relationship between DNA inherited from ancestors and diseases has been scientifically confirmed.
  • Family history is a strong risk factor for disease complexes like cancer, cardiovascular disease, diabetes, autoimmune disorders, and psychiatric illnesses.
  • A person inherits cultural and socioeconomic experiences from family, which can influence their risk of health problems.
  • Forty-six chromosomes (23 pairs) are found in every human cell except reproductive cells.
  • Each chromosome carries genes responsible for physical characteristics like eye, skin, and hair color, height, body type, and intelligence.
  • The human genome contains about 20,000 to 25,000 genes.

DNA Testing

  • Predictive testing: Used to determine if genes associated with hereditary diseases are present.
  • Carrier testing: Identifies if an individual carries harmful genes that can be passed on to offspring.

More Testing

  • Prenatal testing: Used to identify genetic disorders in the fetus (ultrasound, amniocentesis, chorionic villus sampling, maternal blood tests).

Genetic Diseases

  • Permanent changes in DNA (mutations) often cause genetic diseases.
  • Mutations can involve one or multiple genes.
  • Environmental factors (age, smoking, exposure to toxins) can trigger genetic diseases.
  • Genetic diseases can result from abnormalities in chromosome structure or number.
  • Health care professionals can counsel patients about genetic diseases and their testing options.

Genetic Discrimination

  • Therapeutic cloning: Produces copies of embryonic stem cells to repair injured tissues.
  • Reproductive cloning: Exact copies of entire animals.
  • Ethical concerns and objections exist regarding cloning.

Exceptions to the Rule

  • Cloning may be used to produce substances useful in medicine or for animal tissue/organ transplantation.
  • Animal rights proponents object to cloning for human benefit.

Clone Continued

  • Cloning viability varies—only 1 or 2 healthy animals result in approximately 100 attempts.
  • Cloning can cause health problems and possibly early deaths.
  • Scientists don't understand the impact of cloning on mental development.

Ethical Concerns

  • Ethical questions arise about allowing trial and error in human cloning.
  • Issues surrounding family dynamics and financial access to cloning services are considerations.
  • Many states have laws prohibiting human cloning.

Gene Therapy

  • Inserting a normal gene into cells to correct a genetic defect.
  • Gene therapy can help correct genetic defects or block overactive pathways.
  • The treatment of some genetic diseases may involve special diets, vitamins, or other agents.

Gene Therapy Continued

  • Germ-line gene therapy is controversial due to ethical, research, and safety issues.

Infertility

  • 10-15 percent of reproductive-age couples experience infertility.
  • Infertility can result from issues with reproductive structures or processes.
  • Various approaches to address infertility exist, including in vitro fertilization, artificial insemination, and surrogacy.

Surrogate/Adoption

  • A surrogate mother agrees to carry a child to term for another couple.
  • Both gestational and traditional surrogacy exist.
  • Adoption is a legal option for couples to raise children.
  • Child abuse prevention and treatment laws apply to adoption practices.

Children's Rights

  • Common law gives parents the right to make healthcare decisions for their children in many cases.
  • "Parens patriae" gives the state authority to intervene in the best interest of children.
  • Legal rights of newborns are similar to other citizens, but special consideration exists for newborns with severe disabilities.

Abandonment

  • There are many stories of parents abandoning newborns.
  • Safe haven laws allow parents to leave newborns in safe locations without legal repercussions.
