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

β¦ Synopsis
We report on a boy with proximal interstitial deletion of chromosome 4, del(4)(q21. 22q23). The patient was born at term with a low birth weight, flat nasal bridge, micrognathia, wide-spaced nipples, clinodactyly of fifth fingers, overlapping fingers, postaxial polydactyly of the right foot, micropenis, hypospadias, a dermal sinus, and cardiac malformations. He developed psychomotor retardation, seizures, and a liver t u m o r w i t h a n i n c r e a s e d s e r u m β£fetoprotein level and rapid growth. The patient carried a deletion of chromosome 4 involving the 4q21-q22 region that was reported to form a unique syndrome. The absence of central nervous system overgrowth and the presence of a malignant liver tumor are unique to our patient, compared to others with the 4q21-q22 deletion syndrome. The clinical manifestations and relationship between the liver tumor and chromosomal anomaly are discussed. Am. J.

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
We report on a girl with a phenotype and developmental profile initially suggestive of Angelman syndrome. Subsequently she was shown to have an interstitial deletion of the long arm of chromosome 17; [del(17)-(q23.1q23.3)], the smallest unique cytogenetic deletion in this region documented to date.

Two infants with chromosome 22q11 deletion syndrome were noted to have symmetrically enlarged Sylvian fissures on cranial MRI. We compared the size of the Sylvian fissures in neuroimaging studies from 17 other subjects with del 22q11 to agematched disease controls. The mean anterior interopercular d
A 17-year-old boy who was diagnosed with ''Waardenburg syndrome'' showed moderate growth and mental retardation. Chromosome analysis showed an apparent interstitial deletion 4q12q21.1. The mother had a direct insertion of the deleted segment into a chromosome 8. The rearrangement was confirmed to be
