amino acid) called isoleucine. This condition also impairs the body's ability to process ketones, which are molecules produced during the breakdown of fats. Signs and symptoms typically appear between the ages of 6 months and 24 months. Affected children experience episodes of vomiting, dehydration, difficulty breathing, extreme tiredness (lethargy), and occasionally seizures. These episodes, which are called ketoacidotic attacks, sometimes lead to coma. Ketoacidotic attacks are frequently triggered by infections, periods without food (fasting), or increased intake of protein-rich foods. This condition is inherited in an autosomal recessive fashion and is caused by mutations in the ACAT1 gene.Beta-ketothiolase deficiency is an inherited disorder in which the body cannot effectively process a protein building block (
