E71.2
Disorder of branched-chain amino-acid metabolism, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Disorders of branched-chain amino acid metabolism refer to a group of rare genetic conditions that affect the body's ability to process certain amino acids, which are the building blocks of proteins. These disorders can disrupt normal metabolic processes and may lead to a variety of health issues. ICD-10 code E71.2 is used to classify these unspecified disorders, indicating that the exact nature or subtype of the disorder has not been specified.
Causes & Symptoms
Clinical Causes: Genetic mutations passed from parents to children, inherited in an autosomal recessive pattern Defective enzymes responsible for breaking down branched-chain amino acids, such as leucine, isoleucine, and valine Accumulation of these amino acids and their toxic byproducts in the body, especially in the blood and tissues Lack of awareness or diagnosis of the specific subtype due to the rarity or nonspecific symptoms
Key Symptoms: Poor feeding, especially in infants Vomiting and irritability Developmental delay or regression in milestones Lethargy or fatigue Muscle weakness or hypotonia Sweet or abnormal smell of urine or sweat Seizures in severe cases Loss of consciousness or coma if untreated
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of clinical assessment, blood tests, and urine analysis. Newborn screening programs may detect abnormal levels of amino acids, prompting further testing. Molecular genetic testing can identify specific mutations. Tissue biopsies are also used in certain cases to analyze enzyme activity.
Treatment Protocols: Management of these disorders involves dietary modifications to restrict the intake of branched-chain amino acids and prevent accumulation of toxic metabolites. Specialized formulas or amino acid-controlled diets are often prescribed. Additional treatments may include:
