P artial deletion of chromosome 11q was first described by Jacobsen et al(4). Forty-eight patients have been reported during the last 30 years, with var iable break points between 11q11 and 11qter. New phenotypic findings in our patient with the associated 11q deletion are imperforate anus, bilateral c ataracts, and hypoplastic, multilobed lungs.
