Researchers have developed a technique that can identify errors caused by mutations linked to a range of genetic disorders, including forms of muscular dystrophy, Huntington's disease and amyotrophic lateral sclerosis (ALS), which could accelerate accurate diagnosis of these conditions. The technique, developed by researchers led by the University of Cambridge, uses RNA samples stretched into usable shapes and tiny glass holes known as nanopores, to analyze sections of RNA that have multiplied far beyond their normal length.
