Later-onset Fabry disease: an adult variant presenting with the cramp-fasciculation syndrome.
Archives of Neurology 2006 March
BACKGROUND: Classic Fabry disease, an X-linked recessive lysosomal storage disease due to the deficient activity of alpha-galactosidase A, typically presents in early childhood with acroparesthesias, angiokeratomas, hypohidrosis, and corneal dystrophy. The neuropathic pain presumably results from glycosphingolipid accumulation in the vascular endothelium and in small-caliber nerve fibers, and is treatable by enzyme replacement therapy. Later-onset variants with residual alpha-galactosidase A activity lack vascular endothelial involvement and classic symptoms, which lead to the development of cardiac and/or renal disease after the fourth decade of life.
OBJECTIVE: To expand the later-onset Fabry phenotype to include cramp-fasciculation syndrome without small-fiber neuropathy.
METHODS: A 34-year-old man who presented with chronic exercise-induced pain, fasciculations, and cramps of the feet and legs, and his similarly affected mother, were evaluated. Clinical, biochemical, and molecular studies were performed.
RESULTS: Clinical evaluation suggested the diagnosis of Fabry disease, which was confirmed by reduced plasma and leukocyte alpha-galactosidase A activities (8.8% and 13.4% of normal, respectively) due to a missense A143T mutation. His mother was heterozygous for the A143T mutation.
CONCLUSION: The presentation of cramps and fasciculations without apparent small-fiber neuropathy expands the phenotype of later-onset Fabry disease.
