HMG CoA lyase deficiency
Other Names for this Disease
- 3-hydroxy-3-methylglutaric aciduria
- 3-hydroxy-3-methylglutaryl-CoA lyase deficiency
- Defect in leucine metabolism
- HL deficiency
- HMG-CoA lyase deficiency
leucine or make ketones. Ketones are used for energy during periods of fasting. This condition causes episodes of vomiting, diarrhea, dehydration, extreme tiredness (lethargy), and weak muscle tone (hypotonia). During an episode, blood sugar levels can become dangerously low (hypoglycemia), and a buildup of harmful compounds can cause the blood to become too acidic (metabolic acidosis). If untreated, the disorder can lead to breathing problems, convulsions, coma, and death. Episodes are often triggered by an infection, fasting, strenuous exercise, or other types of stress. Mutations in the HMGCL gene cause HMG-CoA lyase deficiency, and this condition is inherited in an autosomal recessive pattern.HMG CoA lyase deficiency is an inherited disorder in which the body cannot process
