    Abstract: Patients with partial trisomy 3p seldom present major dysmorphic features, and holoprosencephaly occurs in only 10% of the cases with partial trisomy 3p. It has been suggested that multiple genetic hits or environmental exposures are required for the clinical expression of holoprosencephaly. At 16 weeks of gestation, prenatal sonography identified a fetus with holoprosencephaly, orofacial clefts, pyelectasis, and a unilateral duplex renal system. Amniocentesis revealed the karyotype of 46,XX,der(11)t(3;11)(p21;q23)pat with partial trisomy 3p (3p21-->pter) and partial monosomy 11q (11q23-->qter). The pregnancy was subsequently terminated. Postnatally, the proband showed hypotelorism, a depressed nasal bridge, orofacial clefts and holoprosencephaly-premaxillary agenesis. The present case provides evidence that partial trisomy 3p/monosomy 11q can be a genetic cause of holoprosencephaly and del(11)(q23-->qter) is associated with a duplex renal system.
