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

โฆ Synopsis
We describe a 7 1/2-year-old girl with mildly unusual phenotype and complex heart disease including ventricular myocardial noncompaction. She was found to have a distal 5q deletion, del(5)(q35.1q35.3). Fluorescent in situ hybridization showed that this deletion included the locus for the cardiac specific homeobox gene, CSX. This suggests that some instances of ventricular myocardial noncompaction may be caused by haploinsufficiency of CSX. Am. J. Med. Genet. 85:419-423, 1999.

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 4-year-old asymptomatic boy was referred for evaluation after being diagnosed with Melnick-Needles syndrome. Echocardiography demonstrated noncompaction of the left ventricular myocardium as an isolated cardiac finding. Though other structural cardiac defects were reported previously in this syndr
Most deletions are terminal encompassing as much as 36 Mb, but interstitial deletions have also been reported. We have evaluated 42 subjects with deletions of 18q at our institution. This is the largest number of individuals with this chromosome abnormality studied by one group of investigators. Her
Tricuspid atresia has not been reported in 22q11 microdeletions causing DiGeorge and velo-cardio-facial syndromes. We investigated the prevalence of 22q11 hemizygosity in 26 children with tricuspid atresia. Fluorescent hybridization with the Sc11.1 probe demonstrated a 22q11 microdeletion in 2 patie
