Gene editing in unborn babies to treat a liver disease

In utero gene editing to cure a metabolic liver disease

NIH-funded research Children's Hosp of Philadelphia · NIH-10771927

This study is testing a new way to fix a genetic problem that causes hereditary tyrosinemia type I, a serious liver disease, by using a special gene editing tool before the baby is born, which could help prevent the disease from causing harm.

What this research studies

This research aims to use advanced gene editing techniques to correct genetic mutations responsible for hereditary tyrosinemia type I (HT1), a severe metabolic liver disease. By applying CRISPR-Cas9 technology in utero, the researchers hope to edit the faulty FAH gene before the baby is born, potentially preventing the disease from causing irreversible damage. The approach focuses on leveraging the unique characteristics of the developing fetus to enhance the effectiveness of the gene editing process. This innovative strategy could offer a new therapeutic option for families affected by this life-threatening condition.

Who could benefit from this research

Good fit: Ideal candidates for this research are pregnant women carrying a fetus diagnosed with hereditary tyrosinemia type I or at high risk for the condition due to family history.

Not a fit: Patients who are already diagnosed with HT1 and have reached adulthood or those who are not pregnant will not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a cure for hereditary tyrosinemia type I, significantly improving the quality of life and survival rates for affected infants.

How similar studies have performed: Other research has shown promise with CRISPR gene editing techniques, but the specific application of in utero gene editing for metabolic liver diseases is still largely novel.
