ADVANCE IN FREIDRICH’S ATAXIAImpaired coordination of voluntary muscle movements. Manifestations can include, among others, slurred speech, poor balance, unsteady walking, falling, and involuntary eye movements (nystagmus). Usual RESEARCH: The CRISPR-Cas9 gene editing technique safely removed the gene expansion that causes Friedrich’s ataxia (FA), allowing for normal frataxin levels and more functional mitochondria in cells taken from patients, an early study reported. This work, and further experiments in mice, supports the potential of a stem cell approach to […]
