Disseminated angiokeratomas can be seen in patients with an inherited deficiency of alpha-l-fucosidase as well as in patients with classic Fabry's disease. Patients with deficiency of this lysosomal enzyme, or fucosidosis, have spasticity, mental retardation, and retardation of growth in addition to angiokeratomas. We herein report three new cases of this rare syndrome.

Fucosidosis, a progressive neurodegenerative disease, evident in early childhood, is associated with progressive loss of mental and motor function and increasing spasticity and hyperreflexia. We report a Canadian male, with clinical features similar to previously reported fucosidosis patients, however, since age 5 he has exhibited progressive dystonic posturing, initially unilateral, but recently involving both lower limbs. Extensive study of his cultured lymphoblasts demonstrated that alpha-fucosidase activity and immunoreactive alpha-fucosidase protein were absent. He is homozygous for the Q422X mutation, a C to T transition within exon 8 of the alpha-fucosidase gene which results in loss of an EcoR1 restriction enzyme cut site. Even among the 4 other reported fucosidosis families having one or more individuals homozygous for this same (Q422X) mutation there was no previous report of dystonia.

Fucosidosis is a rare, autosomal recessive lysosomal storage disorder caused by a severe deficiency of alpha-L-fucosidase. Here we present a 27-month-old male who was referred to us for evaluation of developmental delay, which was first detected at age six months. His past medical history was also remarkable for recurrent pulmonary infections and myoclonic seiures. His family history revealed that he was the first living child from a consanguineous marriage. He had a younger sister who died at five months of age from pneumonia who had facial resemblance to the proband, developmental delay and a congenital heart defect. Physical examination revealed length: 81 cm (25-50p), weight: 10.2 kg (25-50p), and head circumference: 49 cm (50-75p). He had a coarse face, hepatomegaly and generalized spasticity. His initial laboratory examination revealed negative urine screening column chromatography for mucopolysaccharidosis. His X-ray findings were consistent with mild form of dysostosis multiplex. Based on clinical and laboratory features, fucosidosis was suspected. Fucosidase enzyme activity was zero. In addition to fucosidosis, thyroid function tests indicated primary hypothyroidism. This is, to the best of our knowledge, the fourth case of fucosidosis diagnosed in Turkey.

A 4-year-old boy presented with progressive neurodegeneration, mild coarsening of facies and spasticity. The classical neuroimaging guided the subsequent investigation of enzyme assay which confirmed the diagnosis of fucosidosis.
