Children with genetic deafness regain hearing after gene therapy treatment

Breakthrough Treatment Enables Deaf Children to Hear for the First Time

A groundbreaking treatment has transformed the lives of six deaf children, aged one through 11, providing them with the ability to hear the world around them.

These children, hailing from experimental groups in both China and the United States, shared a common genetic mutation that impeded the production of a crucial protein essential for hearing.

Gene Injection Restores Hearing: A Remarkable Journey

In this revolutionary treatment, scientists injected a modified version of the otoferlin (OTOF) gene directly into the inner ear.

This gene, responsible for the production of a vital hearing-related protein, successfully prompted the cells to generate the missing protein.

Astonishingly, the children exhibited notable progress in their hearing abilities within just six weeks after a single injection.

Significant Hearing Improvement in 26 Weeks

After 26 weeks of treatment, the children’s hearing levels reached up to 70 percent of normal.

Captivating progress videos documented heartwarming moments, including a one-year-old responding to his name and a little girl uttering words she could not speak before.

The positive results underscore the transformative impact of this breakthrough on the lives of these previously deaf children.

Testimonials of Success and Future Implications

Aissam Dam, an 11-year-old who underwent the treatment at the Children’s Hospital of Philadelphia (CHOP), experienced hearing for the first time.

Dr. Zheng-Yi Chen, a professor at Harvard Medical School and study author for China’s experiments, emphasized the remarkable nature of the results, emphasizing the potential for preventing abnormal brain development in hearing-impaired children.

Addressing Hereditary Deafness with Gene Therapy

This gene therapy holds promise in addressing hereditary deafness, a condition affecting millions of children globally.

Approximately 60 percent of cases of deafness or hearing loss in children are attributed to genetic factors.

The success story of Aissam Dam and the five children in China showcases the potential of gene therapy to address genetic abnormalities causing hearing impairment.

Mechanism of Treatment and Potential for Future Use

The treatment involved a surgical procedure wherein a modified virus was injected into the cochlea, delivering functional copies of the otoferlin gene.

This approach allowed the hair cells in the inner ear to produce the missing protein, resulting in significant hearing improvement.

Dr. John A. Germiller of CHOP highlighted the potential for gene therapy to address various genes associated with childhood hearing loss.

Global Impact and Continued Progress

The success in the United States and China demonstrates the global significance of this breakthrough in gene therapy for hearing loss.

With gene therapy already approved for certain medical conditions, this treatment offers hope for addressing diverse genetic factors contributing to childhood deafness.

The future holds the promise of expanding this groundbreaking approach to benefit a broader spectrum of individuals experiencing hearing impairment.
