This is the first study to demonstrate reduced MTR in the SCP of individuals with FRDA when compared to control participants. These findings may reflect a process of disruption of the reciprocal relationship between oligodendrocytes and axons resulting in paucity of myelin, and provides significant new insight into the neurodegenerative pathology of FRDA

Thefindings suggest that high dose of sunlight might cause chemical modifications which may have chemical, biochemical, pharmacological and toxicological implications, especially possible undesirable phototoxic effects in patients undergoing treatment in countries with increased sunlight exposure.
