The number of patients heterozygous for terminal deletion of the short arm of chromosome 8 (del8p) has increased progressively in parallel with the improved ability of cytogenetic techniques to recognize small imbalances. A del(8p) syndrome has been outlined. We reported a consistent association wit

β¦ Synopsis
We describe a child with β£-thalassemia ascertained by newborn screening. Evaluation at 9 months of age showed minor anomalies and developmental delay. Chromosomal analysis demonstrated a de novo deletion of the most distal portion of the short arm of chromosome 16, which contains the β£-globin genes. Analysis of the β£globin locus by Southern blot analysis did not demonstrate altered band sizes at this locus; however, analysis of the films using densitometry confirmed hemizygosity. This is the fifth reported case of the ATR-16 syndrome (β£-thalassemia retardation-16) not complicated by duplication or deletion of other chromosomes. Am. J. Med. Genet. 72: 451-454, 1997.

Chromosome imbalance affecting the short arm of chromosome 4 results in a variety of distinct clinical conditions. Most of them share a number of manifestations, such as mental retardation, microcephaly, pre-and post-natal growth retardation, anteverted and low-set ears, that can be considered as no
The Rubinstein-Taybi syndrome (RTS) is a well-defined entity characterized by growth and mental retardation, broad thumbs and halluces, and typical face. The RTS locus was assigned to 16p13.3, and interstitial submicroscopic deletions of this region (RT1 cosmid, D16S237) were initially identified in
