Genetic engineering has a lot of potential in treating diseases where it offers innovative ideas to address different medical challenges.
Below are its main potentials:

Gene Therapy:

1. Object: It is meant to introduce, replace, or edit genes for the purpose of treating or preventing diseases.
2. Applications: Target genetic disorders, inherited conditions and specific types of cancers.
3. Problems: Ensuring gene-targeting accuracy, reducing off-targeting effects and addressing ethical issues.

CRISPR/Cas9 technology:

1. Aim: Use CRISPR/Cas9 mechanism for accurate gene editing.
2. Applications: Correct gene mutations, alter genes and create possible cures for diseases such as sickle cell anemia and cystic fibrosis.
3. Challenges: Off target effects, ethical concerns and safety assessment needs.

Genetically Modified Organisms (GMOs) for Drug Production:

1. Objective: Engineer organisms that produce therapeutic proteins or drugs.
2. Uses: Improve yields of insulin, growth hormone and other biopharmaceuticals.
3. Difficulties: Safety measures, contamination prevention and public worries.

Personalized Medicine:

1. Objective: Medical treatment customized based on individual’s genetic makeup.
2. Implementation: Personalized therapies against cancer, heart disease etc.
3. Problems: Ethical considerations, data privacy and extensive genetic profiling.

Immunotherapy and CART Cells:

1. Purpose: Cancer cells can be targeted using immune cells from a patient which have been modified to strengthen their capacity of killing them
2. Applications: Treating certain types of cancer like leukemia and lymphoma
3. Challenges: Safely managing side effects, yielding optimal therapy plans that lead to complete remission of all malignant cells, overcoming drug resistance

RNA Interference (RNAi):

1. Purpose: Ablate or down regulate specific genes through small RNA molecules
2. Applications: Disease related gene targeting that might treat cases such as Huntington’s disease
3. Challenges: Transporting RNA molecules into target cells, reducing off-target effects and ensuring specificity.

Synthetic Biology:

1. Aim: Designing and building new biological parts or redesigning existing biological systems for human use.
2. Applications: Making synthetic microbes that can act as drug carriers or engineering bacteria for detecting diseases.
3. Challenges: Issues of safety, the environment and ethical considerations.

Viral Vector Development:

1. Purpose: Modified viruses used to introduce therapeutic genes into host cells.
2. Application: Gene therapy delivery; vaccine delivery through viral vectors.
3. Problems: Immune response to viral vectors in vivo, improving transfection efficiency and biosafety consideration.

Drug Discovery and Development:

1. Objective: Speed up drug discovery by targeting specific genes or pathways.
2. Uses: Find new drug targets, improve efficacy of drugs and make it easier to test new molecules.
3. Difficulties: Ensuring target specificity, dealing with unexpected adverse events, and getting through regulatory obstacles.

With advances in research and technology in genetic engineering; however, the potential for innovative disease treatments continues to increase with advancements in research and technology in genetic engineering. Yet, ethical considerations, safety concerns and regulatory frameworks are important factors to consider because this is key to ensuring that application of genetic engineering in healthcare is properly done while taking into account these aspects of ethics, safety issues as well as regulatory frameworks that facilitate responsible application of genetic engineering in health care industry.
