Mutations in the HMGCL gene cause<unk> . The enzyme made by the HMGCL gene plays an essential role in breaking down dietary proteins and fats for energy. Specifically, the enzyme is responsible for processing leucine, an amino acid that is part of many proteins. This enzyme also produces ketones during the breakdown of fats. If a mutation in the HMGCL gene reduces or eliminates the activity of this enzyme, the body is unable to process leucine or make ketones properly. A lack of ketones leads to hypoglycemia, and compounds called organic acids (which are formed as products of amino acid and fat breakdown) can cause the blood to become too acidic. Metabolic acidosis and hypoglycemia impair tissue function, especially in the central nervous system.
