The authors undertook a clinical and genetic study in a large family with the aim of identifying the mode of inheritance of Fabry syndrome and congenital ptosis. These two types of pathology were present to varying extents. The family pedigree consisted of 95 individuals, spanning 5 generations. Three individuals (males) were found to have Fabry syndrome and 14 (males and females) congenital ptosis. The patients with Fabry syndrome also had congenital ptosis. According to these results, Fabry syndrome is inherited by an X-linked recessive mode and congenital ptosis by an autosomal dominant mode.

Corneal clouding is uncommon in infants and children but when present in this age group, it is often associated with mucopolysaccharidoses or Fabry disease. This report describes the case of an 11-year-old male who demonstrated poor weight gain, short stature, segmental myoclonus, and learning problems from 5 years of age followed by general weakness and extremely poor balance. Corneal clouding was evident as a result of a blurred vision complaint at 9 years of age. Both urine metabolic screening for mucopolysaccharidoses and analysis of lysosomal enzymes displayed negative findings. Clinical conditions worsened, including ptosis, progressive weakness, and positive Gowers' sign. Oral glucose lactate stimulation test was positive, therefore a muscle biopsy was performed at 11 years of age. Light microscopy of muscle biopsy disclosed abundant ragged red fibers; electron microscopy revealed abnormal mitochondria in terms of tubular cristae, concentrated cristae, stacking cristae, and round granular patterns of inclusion bodies in the matrix. Thus mitochondrial disease was diagnosed. We conclude that mitochondrial disease should be added to the list of differential diagnosis of corneal clouding in children, especially in cases with normal urine metabolic screening for mucopolysaccharidoses or when assays of lysosomal enzymes appear normal.

Fabry disease is an X-linked lysosomal disorder caused by deficiency of the lysosomal enzyme alpha-galactosidase A. We report on a 32-year-old female patient with an 8-year history of vascular lesions on the hips and periumbilical region and a presumed Fabry disease without positive family history. Ophthalmologic evaluation revealed whorl-like corneal opacities. Echocardiography revealed myxomatous degeneration and prolapse of the mitral valve. DNA analysis of the alpha-galactosidase A gene confirmed the diagnosis of Fabry disease, showing a de novo point mutation at position 691 of exon 5. The patient is now obtaining intravenous enzyme replacement therapy with agalsidase alfa and remains without drug-related reactions.

Fucosidosis is a rare lysosomal storage disorder caused by deficient activity of the enzyme l-fucosidase in all tissues. We presented magnetic resonance imaging [MRI] and MR spectroscopy [MRS] findings of a 4-year-old boy with genetically proven fucosidosis. He had a history and clinical findings of recurrent sinopulmonary infections, hypertonicity on lower extremities, gingival hypertrophy, bilateral ptosis, angiokeratoma corporis diffusum, and dysostosis multiplex. He had no organomegaly and urine glycosaminoglycan analysis were normal. MRI revealed abnormalities within the globus pallidus and periventricular and subcortical white matter. MRS showed a peak at the 3.8-3.9 ppm as a result of accumulating carbohydrate containing macromolecules and another peak at 1.2 which was doublet and inverted on TE 135, suggesting fructose peak. A final diagnosis of fucosidosis was proved by mutational analysis of FUCA1 gene which is responsible for the Fucosidosis phenotype. Two recent reports of MRS of two patients demonstrated that MRS is specific for fucosidosis. In this case, we aim to discuss fucosidosis with MRI and MRS findings accompanied by the literature.
