Friedreich's Ataxia (FRDA) Genetic Expansion (August 2026)
Why in News / Context: In August 2026, geneticists identified ancestral 'protomutations' in the FXN gene that explain why the neurodegenerative disorder Friedreich's Ataxia (FRDA) affects people of Eurasian descent almost exclusively.
Definition: A rare, autosomal recessive, inherited genetic disorder that progressively damages the nervous system and heart, typically starting in childhood.
Significance:
- Abnormal Genetic Expansion: Primarily caused by a massive expansion of GAA trinucleotide repeats within the FXN (frataxin) gene.
- Mitochondrial Defect: The expansion reduces the production of the frataxin protein, which is vital for normal mitochondrial function and iron-sulfur cluster formation.
- Ancestral Lock: Protomutations serving as the expansion reservoir are found exclusively in Eurasian genetic pools, explaining its regional predominance. Currently, no cure exists.
"Friedreich's Ataxia (FRDA), a neurodegenerative disorder found almost exclusively in Eurasian populations, is caused by an abnormal expansion of which trinucleotide repeat?"
Prism Memory Hook
FRDA: GAA repeat expansion in the FXN gene causes Frataxin drop, destroying mitochondria.
