congenital nephrotic syndrome and distinct ocular (eye) abnormalities, including microcoria (small pupils that are not responsive to light). Most affected children have early-onset, chronic renal failure; neurodevelopmental problems; and blindness. Hypotonia (poor muscle tone) and movement disorders have also been reported.
