2. GENETICTESTING
• Genetic testing involves analyzing an individual's DNA to identify genetic
disorders, mutations, or variations.

3. • TYPES OF GENETIC TESTING
1. Diagnostic testing: Identifies the genetic cause of a patient's symptoms.
2. Predictive testing: Determines the likelihood of developing a genetic disorder.
3. Carrier testing: Identifies individuals who carry a genetic mutation that can be
passed to their offspring.
4. Prenatal testing: Screens for genetic disorders during pregnancy.
5. Newborn screening: Tests newborns for genetic disorders.

4. • METHODS OF GENETIC TESTING
1. DNA sequencing: Analyzes the order of DNA building blocks.
2. Chromosomal analysis: Examines the structure and number of
chromosomes.
3. Biochemical testing: Measures the levels of specific proteins or
enzymes.
4. Molecular testing: Analyzes DNA or RNA to identify genetic
mutations.

5. • APPLICATIONS OF GENETIC TESTING
1. Diagnosis of Genetic Disorders: Identifies the genetic cause of a patient's
symptoms.
2. Risk Assessment: Determines the likelihood of developing a genetic disorder.
3. Family Planning: Helps individuals and families make informed decisions
about reproduction.
4. Personalized Medicine: Tailors medical treatment to an individual's genetic
profile.
5. Forensic Analysis: Analyzes DNA evidence in criminal investigations.

6. • BENEFITS AND LIMITATIONS OF GENETIC
TESTING
Benefits:
1. Accurate diagnosis: Identifies the genetic cause of a patient's symptoms.
2. Informed decision-making: Helps individuals and families make informed
decisions about reproduction and medical treatment.
3. Personalized medicine: Tailors medical treatment to an individual's genetic
profile.

undergoing genetic testing.

9. GENETHERAPY
• Gene therapy is a medical treatment
that uses genes to prevent or treat
diseases.
• It involves introducing healthy copies
of a gene into cells to replace faulty or
missing genes.

10. • TYPES OF GENE THERAPY
1. Germline GeneTherapy: Involves making changes to the genes in
reproductive cells, which can be passed on to future generations.
2. Somatic GeneTherapy: Involves making changes to the genes in non-
reproductive cells, which cannot be passed on to future generations.

11. • METHODS OF GENE THERAPY
1. ViralVectors: Using viruses to deliver healthy copies of a gene to cells.
2. Non-ViralVectors: Using liposomes, nanoparticles, or other methods
to deliver healthy copies of a gene to cells.
3. Gene Editing: Using techniques like CRISPR/Cas9 to edit genes
directly.

12. • APPLICATIONS OF GENE THERAPY:
1. Inherited Disorders: Gene therapy can be used to treat inherited disorders, such as sickle
cell anemia and cystic fibrosis.
2. Cancer: Gene therapy can be used to treat cancer by introducing genes that help kill cancer
cells.
3. Genetic Disorders: Gene therapy can be used to treat genetic disorders, such as muscular
dystrophy and Huntington's disease.
4. Viral Infections: Gene therapy can be used to treat viral infections, such as HIV and
hepatitis.

13. • BENEFITS OF GENE THERAPY
1. Potential Cure: Gene therapy can potentially cure genetic disorders.
2. Long-TermTreatment: Gene therapy can provide long-term treatment
for chronic diseases.
3. Reduced Symptoms: Gene therapy can reduce symptoms and improve
quality of life.

14. • CHALLENGES AND RISKS OF GENE THERAPY
1. Safety concerns: Gene therapy can have safety concerns, such as off-target
effects and immune responses.
2. Efficacy: Gene therapy may not be effective for all patients or conditions.
3. Cost: Gene therapy can be expensive and may not be accessible to all patients.
4. Regulatory frameworks: Gene therapy is regulated by various frameworks,
which can vary by country and region.

15. • FUTURE OF GENE THERAPY
1. Advances in technology: Advances in technology, such as CRISPR/Cas9, are improving the
efficiency and accuracy of gene therapy.
2. Increased funding: Increased funding for gene therapy research is helping to advance the field.
3. Growing demand: Growing demand for gene therapy is driving innovation and investment in
the field.
4. Regulatory frameworks: Regulatory frameworks are evolving to accommodate the growth of
gene therapy.

16. GENETIC COUNSELING
• Genetic counseling is the process of
helping individuals and families understand
