The association with genitourinary anomalies and mental retardation is known as WAGR Syndrome. Most patients have prominent lips and macrognathia. Other features may include congenital cataracts, nystagmus, ptosis, and blindness. The presence of ptosis and generalized hypotonia in a subgroup of patients suggests a susceptibility to malignant hyperthermia.
