question: How could U1 small nuclear RNA be used in therapeutics?
answer: Until now, two main types of therapeutic strategies have been developed using U1 small nuclear RNA (snRNA): 1) Production of a defective, but partially functional protein, with the help of exon skipping, through modulation of pre-mRNA splicing, and 2) Correction of pathogenic effects of splice donor site mutations with the use of U1 snRNA adapted to the defective variant.
