Currently there is no effective treatment for FXTAS, and the development of biomarkers is still in its infancy. Recent metabolic studies have provided promising insight through identification of potential biomarkers and therapeutic pathways. Here we review our latest understanding of the metabolic alterations found in FXTAS patients and disease models, along with our perspective for future studies in this emerging field.
