Eye movement may be a helpful measure of disease severity: Review

Objective measures of eye movement abnormalities are associated with measures of disease severity in Friedriech’s ataxia (FA) and other hereditary ataxias, a new study reports. “We have shown that characteristic oculomotor [eye movement] abnormalities can be quantified by the use of eye movement recordings in hereditary ataxias, and that…

New Mouse Models Developed of Rare Mutation Seen in Some Patients

Researchers have developed and characterized mouse models of Friedreich’s ataxia (FA) carrying a rare disease-causing mutation, a study reports. The rare FXN gene mutation, dubbed G130V, is found in some FA patients alongside the common gene expansion defects seen in most cases. These patients experience less severe symptoms and…

Early Data Support Gene-editing Platform’s Ability to Fix FA Deficits

Prime Medicine’s gene-editing technology — called Prime Editing — successfully corrected the genetic deficits associated with Friedreich’s ataxia (FA) and restored nerve cell projections in preclinical studies using patient cells, the company has announced. The company also announced positive updates from a number of its 18 other developmental programs…

Spinal Cord Abnormalities Correlate With Disease Severity in FA

People with Friedreich’s ataxia show marked abnormalities in the structure of the upper spinal cord, some of which are correlated with measures of disease duration and severity, a study reports. “These results provide new insights about [the development of Friedreich’s ataxia] and indicate that spinal cord MRI may be…

DT-216 Safely Doubles FXN Gene Activity in FA: Phase 1 Trial Data

The investigational therapy DT-216 safely worked to more than double the activity of the FXN gene — involved in energy production in cells — in people with Friedreich’s ataxia (FA). That’s according to new data from a single-ascending dose (SAD) Phase 1 clinical trial, which showed the treatment candidate was…

$4.8M Grant Supports Work Into Gene Editing Treatment for FA

A $4.8 million grant from the California Institute for Regenerative Medicine (CIRM) will support a research project hoping to move a one-time gene editing treatment for Friedreich’s ataxia closer to clinical trials. “If successful, this approach could prevent the neurologic and cardiac complications in [Friedreich’s ataxia] and address the pressing…

Diabetes Linked to Worse COVID-19 Outcomes in FA Patients

People with Friedreich’s ataxia (FA) who also have diabetes, a condition that causes their blood glucose (sugar) level to become too high, are more likely than those who don’t have diabetes to have worse outcomes from COVID-19, according to a single-center study. Having diabetes increased both the chance of…
