In 5% of patients the typical GAA expansion is present in only one fxn allele and a missense mutation is found in the other allele. the disease course in these patients can be as severe as for patients with two expanded alleles.
The Alteration of the C-terminal Region of Human Frataxin Distorts its Structural Dynamics and Function in L198R mutant, or its complete truncation in FXN 81-193 causes FRDA.
