E71.5
Peroxisomal disorders
Clinical Classification Guidelines
Excludes Type 1
- Schilder's disease (G37.0)
Medical Intelligence & Overview
Peroxisomal disorders are a group of rare inherited conditions caused by problems with peroxisomes—tiny structures inside cells that help break down fats and detoxify harmful substances. These disorders can affect multiple parts of the body, including the brain, liver, and muscles, leading to a variety of health issues. Because of their complexity and rarity, understanding these conditions is important for early recognition and management.
Causes & Symptoms
Clinical Causes: Genetic mutations inherited from parents Disorders passed down in an autosomal recessive pattern, meaning a person must inherit two copies of the faulty gene Defects in genes that encode for peroxisomal proteins Certain mutations disrupt the formation or function of peroxisomes, impairing their ability to process specific fats
Key Symptoms: Developmental delays or intellectual disability Growth problems and failure to thrive in infants Liver enlargement (hepatomegaly) Muscle weakness or low muscle tone Seizures or neurological symptoms Vision and hearing impairments Facial abnormalities, such as high forehead or flat face Problems with the eyes, including abnormal eye movements or cataracts Elevated levels of very long-chain fatty acids in the blood
Diagnostic & Treatment
Diagnosis Path: Diagnosis often involves a combination of clinical evaluation and specialized tests. Blood and urine tests can detect abnormal levels of certain fats, such as very long-chain fatty acids. Imaging studies like MRI may reveal brain abnormalities. Genetic testing can identify mutations in specific genes associated with peroxisomal disorders. Some cases may require a skin biopsy to examine peroxisome structure and function directly.
Treatment Protocols: Nutritional support to address growth and development needs Medications to manage seizures or neurological symptoms Regular monitoring of organ function, especially the liver and brain Supportive therapies such as physiotherapy, occupational therapy, and speech therapy In some cases, specialized diets or supplements are recommended to reduce the accumulation of harmful fats
