E75.23
Krabbe disease
Clinical Classification Guidelines
Medical Intelligence & Overview
Krabbe disease, also known as globoid cell leukodystrophy, is a rare and often fatal genetic disorder that affects the nervous system. It primarily impacts infants and young children, although cases in adults have been reported. The disease is characterized by the progressive destruction of myelin, the protective covering of nerve fibers, leading to severe neurological problems.
Causes & Symptoms
Clinical Causes: Inherited genetic mutation in the GALC gene Autosomal recessive inheritance pattern, meaning both parents must carry and pass on the defective gene for a child to develop the condition Lack or deficiency of the enzyme galactocerebrosidase (GALC), which is essential for breaking down certain fats in the nervous system
Key Symptoms: Irritability and feeding difficulties in infants Muscle stiffness and weakness Developmental delays Seizures Loss of vision and hearing Poor muscle tone (hypotonia) Difficulty swallowing Progressive paralysis Enlarged spleen and liver (less common in early stages)
Diagnostic & Treatment
Diagnosis Path: Newborn screening tests to detect enzyme deficiency Blood tests to measure GALC enzyme activity Genetic testing to identify mutations in the GALC gene Neuroimaging studies, such as MRI, to observe brain deterioration Examination of nerve tissue, if necessary
Treatment Protocols: Hematopoietic stem cell transplantation (bone marrow transplant) may slow disease progression in early stages Supportive therapies like physical, occupational, and speech therapy Management of seizures and nutritional support Experimental gene therapy approaches under research
