This article reports a 7-year-old female with septo-optic dysplasia and congenital hepatic fibrosis. She manifested nystagmus and severe hepatosplenomegaly. Brain magnetic resonance imaging revealed agenesis of the septum pellucidum, optic nerve hypoplasia, pituitary gland stalk hypoplasia, and absence of the posterior pituitary gland. She was diagnosed with growth hormone deficiency, hypothyroidism, diabetes insipidus, and adrenal insufficiency. Thus, this case was regarded as septo-optic dysplasia. No mutation was evident in the coding and boundary regions of the homeobox gene HESX1. Percutaneous biopsy of the liver demonstrated the presence of broad septa of fibrous tissue containing abundant bile ducts without inflammatory cell infiltrates, a finding compatible with congenital hepatic fibrosis. Although there is an association between septo-optic dysplasia and neonatal cholestasis, believed to be related to hypopituitarism, this case of septo-optic dysplasia with congenital hepatic fibrosis is apparently the first reported in the English literature.

Axenfeld-Rieger spectrum (ARS) includes the anterior segment abnormalities posterior embryotoxon, irido-corneal adhesions, corectopia, and other abnormalities of pupil size and shape. Glaucoma occurs in approximately 50% of affected children. It is often caused by mutations of FOXC1 or PITX2. Timing of expression and dosage of these transcription factors appear to be very critical in the development of the anterior segment. We report on one child with a deletion and another with a duplication involving 6p25, causing an anirdia-like phenotype. Classic anirdia is a pan-ophthalmic disorder caused by heterozygous mutations involving the paired homeobox gene PAX6 at 11p13. It is often associated with optic nerve hypoplasia, foveal hypoplasia, corneal pannus, nystagmus, and cataract. Microdeletion of 11p13 may be associated with life threatening Wilms tumor. Distinguishing these two syndromes has critical implications for prognosis and treatment. We demonstrate how chromosomal microarray can be instrumental in differentiating these phenotypes.
