Millions globally suffer from rare diseases, often genetic and affecting children. This study explores using antisense oligonucleotides to fix incorrect RNA splicing, a common result of disease-causing genetic mutations. The results showed that tailored ASOs could correct incorrect splicing for various mutation types, showing this technology′s potential in treating rare genetic diseases. The team chose five mutation types disrupting normal splicing and created specific ASOs to correct these errors in cell models. They created minigenes to simulate the mutations and tested different ASOs′ effectiveness. This method was key to understanding ASOs′ ability to restore normal gene function, crucial for developing targeted treatments for rare genetic disorders. This research could lead to new, targeted treatments for rare genetic disorders, offering hope to millions of patients and their families facing limited treatment options. This summary was initially drafted using artificial intelligence, then revised and fact-checked by the author.
