Kabuki syndrome is a multiple congenital anomaly/mental retardation syndrome with a diagnosis that is dependent upon clinical findings. Recognition of this entity is based upon unique facial appearance, including long palpebral fissures with everted lower eyelids, arched eyebrows, fleshy-cup-shaped ears and trapezoid philtrum, postnatal growth retardation, and mild to moderate mental retardation. We here report a seven-year, seven-month-old male patient with Kabuki syndrome who also had agenesis of the left kidney. We draw attention to the frequency and diversity of urogenital anomalies in this syndrome.
