Collapsing glomerulopathy in Galloway-Mowat syndrome: a case report and review of the literature.
The Galloway-Mowat syndrome (GMS) (MIM251300) is described as an autosomal recessive disorder, the gene of which has not yet been identified. We report the case of a boy presenting with an early nephrotic syndrome, microcephaly, seizures, and psychomotor retardation. He died at 3 years and 11 months in a context of end-stage renal function consistent with a GMS. He was the second child of a non-consanguineous marriage. There was no family history of nephrotic syndrome or end-stage renal failure, but his mother had a moderate mental retardation complicated by seizures. He presented dysmorphologic features, including micrognathia and large and floppy ears. Renal biopsy showed a focal segmental glomerulosclerosis with a collapsing glomerulopathy and abundant visceral epithelial cell proliferation. The majority of the glomeruli were sclerotic. We report the first case of GMS associated with a collapsing glomerulopathy.
