E71.12
Disorders of propionate metabolism
Clinical Classification Guidelines
Medical Intelligence & Overview
Disorders of propionate metabolism are a group of rare genetic conditions that disrupt the body's ability to process certain amino acids and fats. Propionate is a crucial compound that results from breaking down parts of foods like dairy, meat, and some vegetables. When the body's metabolic pathways are impaired, harmful substances can build up, potentially leading to serious health issues. These disorders are classified under ICD-10 code E71.12 and require careful management to prevent complications.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting enzymes involved in propionate breakdown Inherited metabolic defects passed from parents to children Mutations in genes like PCCA, PCCB, or other related genes integral to propionate metabolism
Key Symptoms: Vomiting and failure to thrive in infants Lethargy and weakness Hypoglycemia (low blood sugar) Muscle weakness or hypotonia Seizures Developmental delays or intellectual disability Difficulty feeding in early infancy Metabolic acidosis (excess acid in the body), which can cause rapid breathing and confusion
Diagnostic & Treatment
Diagnosis Path: Diagnosis often involves a combination of laboratory tests and clinical assessments, including: - Blood and urine tests to detect abnormal levels of propionate and related metabolites - Enzyme activity assays to identify deficiencies in specific enzymes - Genetic testing to pinpoint mutations in relevant genes - Newborn screening programs in some regions can identify these disorders early and facilitate prompt intervention
Treatment Protocols: Management of disorders of propionate metabolism aims to control symptoms and prevent metabolic crises. Approaches include: - Dietary restrictions, limiting intake of foods high in certain amino acids (like valine, isoleucine, methionine, and threonine) - Supplementing with special formulas that are reduced in problematic amino acids - Use of medications such as biotin or carnitine, which may support metabolic pathways - Regular monitoring of metabolic status through blood and urine tests - Emergency interventions during metabolic crises to stabilize the individual - Long-term care may involve multidisciplinary teams including metabolic specialists, dietitians, and neurologists to address ongoing health needs
