Additional Information:

Clinical Description OMIM Tein et al. (1991) reported a 16-year-old girl with 3-hydroxyacyl-CoA dehydrogenase deficiency resulting in juvenile-onset recurrent myoglobinuria, hypoketotic hypoglycemic encephalopathy, and hypertrophic/dilated cardiomyopathy. Biochemical analysis showed that HADH enzyme activity was markedly decreased in skeletal muscle cells, whereas ...
Molecular genetics OMIM In a patient with HADH deficiency presenting as fulminant hepatic failure, O'Brien et al. (2000) identified compound heterozygosity for 2 mutations in the HADH gene (601609.0001; 601609.0002).
