Neurodevelopmental profiles of children with very long chain acyl-CoA dehydrogenase deficiency diagnosed by newborn screening

Abstract

Background: Very long chain acyl-CoA dehydrogenase (VLCAD) deficiency is a disorder of fatty acid oxidation with an estimated incidence of between 1:31,500 and 1:125,000. There is limited information regarding neurodevelopmental outcomes, probably because the disorder is perceived as affecting the skeletal and heart muscles, and many children are deemed asymptomatic.
