Clinical Genetics

Clinical Genetics is the study, diagnosis and management of inherited diseases and abnormalities. Morbidity and Mortality are two concepts that are required to begin understanding Clinical Genetics.


  • Illness and its extent.
  • Fact of being ill
  • Proportion of being ill
  • Mortality

  • Death
  • Proportion of death
  • Not accurately determined
  • Major causes of Morbidity and Mortality in Western Countries

    [1] Cardiovascular Disease -
  • Heart Disease
  • Stroke
  • Atherosclerosis

  • [2] Cancer -
  • Lung Cancer
  • Breast Cancer
  • Bowl Cancer

  • [3] Accidents
    [4] Diabetes
    [5] Suicide

    Major causes of Morbidity and Mortality in Developing Countries

    [1] Lower, Respiratory Infections
    [2] Diarrohoea Disease
    [3] Parasite Infection

    Glossary of terms in Medical Genetics

  • Agarose: A polysaccharide obtained from agar that is the most widely used medium for gel electrophoresis procedures.
  • Bioluminescence: living beings emitting light; "fireflies are bioluminescent".
  • Chromosome: A linear end-to-end arrangement of genes and other DNA, sometimes with associated protein and RNA.
  • E. Coli: Common bacterium that geneticists have studied intensively because of its small genome size, normal lack of pathogenicity, and ease of growth in the laboratory.
  • Electrophoresis: A technique for separating the components of a mixture of charged molecules (proteins, DNAs, or RNAs) in an electric field within a gel or other support.
  • Media: Materials on (or in) which experimental cultures are grown.
  • Plasmid: An autonomous self-replicating genetic particle usually of circular double-stranded DNA.
  • Polymerase: An enzyme that catalyzes the formation of DNA and RNA from an existing strand of DNA or RNA.
  • Reagents: A substance used in a chemical reaction to detect, measure, examine, or produce other substances.
  • Spectrophotometric: The art of comparing, photometrically, the brightness of two spectra, wave length by wave length; the use of the spectrophotometer.
  • Vibrio fischeri: A marine bacterium.
