Patients with trisomy (1)(q42-qter) present with psychomotor retardation, macrocephaly, occasional presence of facial capillary naevi, cardio-vascular anomalies and small size for gestational age. We report on a girl with the same pattern of malformations, who has pure trisomy 1q43: duplication of the region (1) (q43) and the translocation of the terminal region of the other chromosome 1 to the derivative 1, narrowing down the critical region for the characteristic traits of severe developmental delay, macrocephaly and congenital cardiac malformations.
