  • Rearrangements in Cancer Cells Chromosomal breaks produce fusion genes These cause leukemias and lymphomas D iagnosis determines treatment and prognosis
  • Rearrangements in Cancer Cells
    • Lymphocytic Leukemia
    • t(9;22) : BCR - ABL
    • t(12;21) : TEL - AML1
    • t(1;19) : E 2 A - PBX1

  • Diagnosis of genetic diseases
    • - Somatic rearrangements in cancer
    • - Genetic risk factors
    • Pharmacogenetics
    • - Mutations in monogenic diseases
  • Genetic Risk Factors
    • Monogenic diseases are caused by a
    • deleterious mutation in a single gene:
    • Disease-causing mutations
    • Multifactorial diseases are caused by a
    • combination of variations in multiple genes:
    • Genetic Risk Factors
  • Genetic Risk Factors
    • Deep venous thrombosis
    • Cardiovascular disease
    • Alzheimer disease
    • Osteoporosis
  • Genetic Risk Factors
    • Most single risk factors
    • have NO clinical significance
    • in individual patients
  • Genetic Risk Factors
    • Deep venous thrombosis
            • Factor V
            • Factor II
            • MTHFR
