A case of partial 14q- with facial features of holoprosencephaly and hydranencephaly.
We report a rare case of facial features of holoprosencephaly associated with hydranencephaly, with a de novo proximal interstitial deletion of the long arm of chromosome 14, specifically, del(14)(q13q21). She was born at 37 weeks of gestation and transferred to our institution at 3 years of age. The patient had midline facial anomalies consisting of cleft palate, defective nasal septum, and hypotelorism, together with endocrine abnormalities such as diabetes insipidus and hypothyroidism. Cranial computed tomography revealed the near-total loss of all cerebral tissue, with a frontal part of the cerebral falx lacking. None of the few reports of holoprosencephaly with 14q- chromosomal abnormality describe holoprosencephaly in association with hydranencephaly. The partial deletion of chromosome 14, del(14)(q13q21), may underlie the association of facial features of holoprosencephaly and hydranencephaly.
