Researchers studied three siblings who suffered from a severe, fatal disorder starting at birth. They examined cells from these patients and compared them to cells without the specific gene involved. The study aimed to understand how a new genetic change affects cell function.
The scientists discovered that the new genetic change caused major problems in the cells, including broken-down energy production and unusual fat buildup. When they tried to fix the gene in the lab, the cells still did not function properly. However, using a specific drug approach did help improve the cell defects in the lab setting.
This study was very small, involving only three patients, and used lab models like fruit flies to support the findings. Because the disorder is so severe and rare, these results cannot yet be used to treat patients. The main takeaway is that this drug approach might one day offer a new way to treat this specific type of genetic disease, but it needs further testing.
