- Individuals with late-onset VLCAD deficiency typically experience mild symptoms beginning in adolescence or adulthood. (myriad.com)
Strenuous exercise1

- New research into VLCAD and other fatty oxidation disorders has led to the development of new types of therapies that can help stem the effects of the disease, which, without intervention, can lead to heart, muscle or liver damage and a risk of death in more severe cases. (mitocanada.org)
- Fatty oxidation disorders are rare - their combined incidence ranges from 0.9 to 15.2 per 100,000 people - and many doctors simply don't see enough patients with VLCAD, or another type of LC-FAOD, to be familiar with the symptoms. (mitocanada.org)
- On the other hand, rhabdomyolysis triggered by fasting, fever, or physical activity usually occurs in patients with disorders affecting intramitochondrial fatty acid transport and β-oxidation, such as carnitine palmitoyltransferase II deficiency (CPT2), mitochondrial trifunctional protein deficiency and very-long-chain acyl-CoA dehydrogenase deficiency (VLCAD). (ac.ir)
Childhood-onset1
