We report on a fetus and a newborn, both with partial trisomy 7q21-->qter due to different familial translocations, t(7;21)(q21.2;p12) and t(4;7)(q35;q21.2). Postmortem examination of the 19-week-old female fetus disclosed dysmorphic features, cleft palate, anomalies of the great vessels, intestinal malrotation and uterus bicornis. The newborn girl revealed a pattern of minor anomalies, cleft palate, cerebellar hypoplasia, and anomalies of pancreas, gall bladder and appendix. The clinical findings in three other reported fetuses with partial trisomy 7q described so far are reviewed. A duplication 7q21-->qter, as found in the propositi, has only been described in 11 patients who all had a concurrent partial monosomy. Patient 1 is particularly interesting since she is, to our knowledge, the first reported case with pure trisomy 7q21/22-->qter. We reviewed the phenotype of the previously described patients, compared it with the propositae, and summarized the clinical features of pure trisomy 7q21/22-->qter.
