Antisense oligonucleotides show promise in rare autism-linked genetic disorders

In laboratories and clinics at the frontier of rare disease medicine, researchers are learning to speak the language of individual mutations — designing short synthetic strands of DNA that can silence or redirect the very genes responsible for a child's seizures and developmental struggles. Two new studies demonstrate that antisense oligonucleotides are not merely experimental curiosities but tools capable of reducing seizures and restoring language in children with conditions so rare that the entire patient population might fit in a single room. The work signals a broader transformation in me
