We report two brothers with microcephaly, cerebellar atrophy, and focal segmental glomerulosclerosis. The elderbrother showed nephrotic syndrome from 2 years of age and died of renal failure at 8 years of age. The younger brother showed mild proteinuria from 2 years of age, and his renal function was still preserved at 15 years of age. We propose that our patients may be affected with a mild form of Galloway-Mowat syndrome or another autosomal recessive syndrome with focal segmental glomerulosclerosis and central nervous system abnormalities.
