Interestingly, the rare, but predicted as deleterious HADHA variant is associated with long-chain 3-hydroxyl-CoA dehydrogenase (LCHAD) deficiency (OMIM: 609016), but malabsorptive diarrhea is not associated with this condition. This evidence concerns the gene HADHA and long chain 3-hydroxyacyl-CoA dehydrogenase deficiency.
