A heterozygous female with Fabry disease due to a novel alpha-galactosidase A mutation exhibits a unique synaptopodin distribution in vacuolated podocytes.

[fabry disease]

We report the case of a 42-yearold woman diagnosed with heterozygous Fabry disease (FD) due to a novel alpha-galactosidase A Pro210Ser mutation and exhibiting a unique distribution of synaptopodin within podocytes. The patient was referred to our hospital with moderate proteinuria, and a renal biopsy was performed. Light microscopic examination of the specimen revealed diffuse global enlargement of podocytes, which also showed foamy changes. Electron microscopy revealed abundant myeloid bodies in podocytes and focal mitochondrial abnormalities within the tubules. The patient exhibited none of the characteristic symptoms of FD except hypohidrosis and had no obvious family history. Genetic analysis revealed a novel missense mutation (Pro210Ser) in the α-galactosidase A gene. She was ultimately diagnosed with FD based on immunohistochemical staining indicating large amounts of accumulated globotriaosylceramide in her podocytes, detection of urinary globotriaosylceramide secretion using high-performance thin-layer chromatography/ immunostaining, and structural modeling of the mutated alpha-galactosidase A (Pro210Ser). Immunostaining of the swollen and foamy podocytes using podocyte-associated antibodies (against podocalyxin, Wilms tumor-1, vimentin, and synaptopodin) revealed a unique distribution of synaptopodin surrounding globotriaosylceramide. To our knowledge, this is the first report of immunohistologically detected synaptopodin upregulation in foamy podocytes in a patient with FD.
