Abstract
The combination of microcephaly, gyral abnormalities, developmental delay, and a glomerulopathy constitutes a recognizable syndrome. The inheritance is autosomal recessive. Additional abnormalities may include seizures, minor facial anomalies, and hiatal hernia. Onset of proteinuria often occurs in the first 3 months of life, but always before age 3 years. A uniform pattern of renal histologic changes has not been found. There is no effective treatment for the neurologic or renal manifestations of this condition. The prognosis is extremely poor; every patient but one has died before age 5½ years. Antenatal diagnosis may be possible.
