If a person is born with a hereditary disease, which corrective therapy be taken for such a disease

Answer

**Step-by-Step Solution:**

1. **Understanding Hereditary Diseases**: Begin by recognizing that hereditary diseases are genetic disorders passed down from parents to offspring. These diseases are caused by mutations or abnormalities in genes.

2. **Identifying Corrective Therapies**: The primary corrective therapy for hereditary diseases is gene therapy. This approach aims to treat or prevent diseases by modifying the genes responsible for the disease.

3. **Mechanism of Gene Therapy**: Gene therapy can involve various techniques, such as:
- **Gene Replacement**: Replacing a faulty gene with a healthy one.
- **Gene Editing**: Correcting the mutations in the gene using technologies like CRISPR.
- **Gene Addition**: Adding a new gene to help combat the disease.

4. **Application of Gene Therapy**: Gene therapy can be applied at different stages, including:
- **Embryonic Level**: Intervening before the birth of the child to correct genetic defects.
- **Postnatal Level**: Treating the individual after birth to manage or cure the disease.

5. **Historical Context**: The first successful application of gene therapy was performed on a four-year-old girl suffering from Severe Combined Immunodeficiency (SCID), demonstrating the potential of this therapy to treat genetic disorders effectively.

6. **Conclusion**: For a person born with a hereditary disease, gene therapy is the most appropriate corrective therapy to address the underlying genetic issues.
