Abstract(s)

Mitochondrial fatty acid oxidation (FAO) plays a pivotal role in energy homeostasis, namely during periods of fasting or metabolic stress. FAO defects are a group of inherited metabolic disorders that encompass at least twelve distinct enzyme or transporter deficiencies, and can present with a wide range of clinical symptoms with various degrees of severity. Besides recent advances, many doubts still remain on the degree and characteristics of mitochondrial dysfunction on FAOD and its contribution to the clinical phenotype.
