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

β¦ Synopsis
We describe an 11-year-old boy of Saudi origin with an interstitial deletion in the short arm of chromosome 4 (p15.32p16.3) as determined by G-banding and fluorescent in situ hybridization. His clinical manifestations were similar but not identical to previously reported cases of interstitial deletion in the same chromosomal region, and were not those associated with Wolf-Hirschhorn syndrome. The boy had normal facial characteristics, short stature, minor anomalies of hands and feet, amblyopia of the right eye, bilateral hearing loss, and hypotonia. On developmental testing, he had borderline intelligence, with a severe sensory integration and motor planning disorder, and severe deficits in the communication domain. In addition, he had severe oligodontia affecting his secondary dentition. This finding supports the presence of one or more genes involved in dentition in this chromosomal region.
