COMPASSIONATE ALLOWANCE INFORMATION

FUCOSIDOSIS- TYPE I

ALTERNATE NAMES

Alpha-L-Fucosidase Deficiency; ALF; Fucosidosis Infantile Type; Fucosidosis Severe

DESCRIPTION

Fucosidosis Type I is a rare genetic disease that affects the brain, spinal cord, and many other organs, resulting in cellular death. Type I (infantile onset) is the most severe type, with manifestations starting around 10 months of age (range 3-18 months) with progressive dysfunction of the affected organs. Symptoms and signs include progressive psychomotor and neurological deterioration; seizures, spasticity, joint contractures, abnormal bone development, enlargement of the heart, liver and spleen, and delayed growth.

DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM CODING

Diagnostic testing: Urine testing that is positive for the presence of oligosaccharides (partially broken down sugars); Absent or deficiencies in activity of the enzyme alpha-L-fucosidase in blood or skin samples confirms the diagnosis.

Physical findings: Distinct facial features such as, flat face, depressed nasal bridge, and bulging forehead; spasticity, mental and motor deterioration; and abnormal posture (bent arms, clenched fists, and legs held out straight, arms that are bent toward the body and wrists, and fingers that are bent and held on the chest). A characteristic “cherry red spot” may be noted on the retina.

ICD-9: 271.8

ONSET AND PROGRESSION

Pulmonary infection and neurological deterioration are the major causes of death, usually by age 10 years.

TREATMENT

Currently there is no cure for this disorder. Bone marrow transplantation (BMT) has been tried on an experimental basis, but not enough information is available to know if BMT is an effective treatment option.

SUGGESTED PROGRAMMATIC ASSESSMENT*

Suggested MER for evaluation: Clinical history and physical examination that describes the diagnostic features of the impairment, documentation of mental and motor deterioration, seizures, skin findings, facial features, etc. Laboratory investigation should include identification of the deficient enzyme activity in leucocytes, urine or skin fibroblasts.
