Abstract
We report sporadic occurrence of deletion of the long arm of chromosome 11 (q23 β qter) in a male newborn infant with intrauterine growth retardation, craniofacial, cardiac, and orthopedic abnormalities and neonatal death but without genital abnormalities. This deletion is seen predominantly in females; here we emphasize the importance of an XX sex chromosome constitution as a factor determining phenotypic expression of and survival in the del(11q) syndrome. We also provide a description of the cardiovascular system from postmortem examination. The cardiac findings are similar to those of two previously autopsied cases and will assist in early clinical diagnosis of the 11qβsyndrome.

We read with interest the paper by Leana-Cox et al. [1996] which reported on 5 families with recurrent Di-George/velocardiofacial syndrome and deletions of chromosome 22q11 (del22q11), and which reviewed the pertinent literature. The authors observed that up to 25% of del22q11 are inherited. Particu
A newborn boy with complex congenital heart disease, unilateral renal agenesis, and hypocalcemia was found to have a submicroscopic deletion of 22q11.2 (DiGeorge anomaly). In evaluating the pathogenesis of the hypocalcemia, repeatedly elevated or normal levels of parathyroid hormone were found, cons
