Emerging phenotype of duplication (7p): a report of three cases and review of the literature.
Here we report on three patients with dup (7p) and review the previously published 17 cases. Characteristic manifestations include severe/profound psychomotor retardation, dolichocephaly or microbrachycephaly, gaping fontanels and wide sagittal and metopic sutures, hypertelorism, large apparently low-set ears, micrognathia, choanal atresia/stenosis, hyperextensible joints subject to dislocation, joint contractures, and a high rate of cardiac septal defects. Our analysis suggests that dup(7p) is associated with a recognizable characteristic phenotype.
