Is gene therapy currently available to everyone?

The direct answer is no; gene therapy is not currently available to everyone, nor is it a routine treatment for all types of diseases [1]. Although this medical field is developing rapidly and holds great promise, its actual use is restricted to a very limited number of specific conditions that have undergone intensive clinical studies to ensure their safety and efficacy, and have received approval from regulatory bodies [1] [3].

The availability of these treatments depends on whether the disease is caused by a specific genetic defect that can be targeted, as well as the existence of an approved treatment protocol for that defect. Currently, these advanced techniques are mostly used in the context of treating rare genetic diseases or specific types of cancers, and not as a general preventive or therapeutic procedure for the public [1] [3].

Why is gene therapy still limited in availability?

Gene therapy techniques face scientific and logistical challenges that make it difficult to provide them on a large scale at the present time:

• Technical complexity: Gene therapy requires high precision in delivering genetic material to target cells, whether through modified viral vectors or genome editing technologies such as CRISPR-Cas9, to ensure the restoration of protein function without causing additional genetic errors [2].
• Health risks: There remains concern regarding serious immune reactions, as the immune system may attack the vectors used in treatment or the new genetic material, in addition to the risk of unintended effects on other genes that could lead to new health problems [1] [2].
• High costs: Gene therapies are currently among the most expensive treatment options available, which poses a significant barrier to their accessibility and availability to everyone as a routine option [1].

Conditions for which gene therapy is available

So far, approval for gene therapy has been limited to specific clinical cases, including:

• Certain genetic disorders: Such as spinal muscular atrophy and genetic conditions causing vision loss, like Leber congenital amaurosis [1].
• Cancers: Certain gene therapy techniques are used, such as CAR T-cell therapy, where the patient's own cells are modified to fight the disease [1] [3].

How to proceed and look for treatment options

If there is a family history of a genetic disease or an injury involving a complex genetic condition, the first step is always to consult a specialized geneticist or a specialized national center. These specialists are the only ones who can determine whether ongoing clinical trials might represent an available option for your specific case. You should never look for experimental treatments outside of formal medical frameworks, as unapproved gene therapy techniques may carry serious and unexpected risks to the patient.

In the event of receiving any treatment or participating in a clinical trial, any unusual symptoms must be monitored, such as sudden fever, difficulty breathing, or unexplained swelling, which are signs that may indicate an immune response requiring immediate medical intervention. Remember that continuous clinical follow-up is the only standard to ensure patient safety during these delicate processes [1] [2].
