The Galloway syndrome is a rare autosomal recessive disease consisting of congenital microencephaly associated with congenital nephrotic syndrome, and in some cases with hiatus hernia [Galloway and Mowatt, 1968]. The case presented is that of a microencephalic infant with the nephrotic syndrome who died at 11 3/4 months after a course characterized by convulsions, developmental delay, hypotonia and hyperreflexia. Brain weight was 270 g. The frontal, parietal, and rostral temporal cortex was pachygyric. Microscopically there was lack of cortical stratification, immature cortical neurons, improper orientation of cortical neurons (seen in the Golgi stained sections), and glioneuronal ectopias in the leptomeninges. There was hypomyelination in the brain stem and spinal cord, and no myelin in the hemispheres. There was also complete absence of the internal granular layer of the cerebellum. The dentate gyrus within the hippocampal formation was absent and the inferior olivary nuclei were hypoplastic. The mechanism of neuronal migration abnormalities and the significance of associated nephrosis is discussed.

The Galloway-Mowat syndrome, a rare inherited disorder, is characterized by congenital microcephaly with hypotonia and developmental delay, often hiatus hernia, and nephrotic syndrome manifested in infancy or in early childhood. The glomerular lesion has been poorly characterized in the few previous reports of this syndrome. We studied three siblings with microcephaly and nephrotic syndrome occurring during the first two weeks of life. Hematuria, glycosuria and renal failure were also present. Renal biopsy and postmortem specimens of two patients were studied. Glomerular structure was disorganized; capillary lumina were of varying calibers, capillary walls were adherent to one another, and mesangial zones were poorly demarcated. Glomerular basement membrane ultrastructure was markedly altered. The normal trilaminar structure was obscured or replaced by flocculent material; furthermore, 6 to 8 nm fibrils of unknown nature permeated the space between endothelial and epithelial cells. Non-glomerular basement membranes were unaltered in appearance. This syndrome apparently represents, in part, a new disorder of glomerular basement membrane formation and function.
