Oculo-auriculo-vertebral (Goldenhar) spectrum associated with pericentric inversion 9: coincidental findings or etiologic factor?

Oculo-auriculo-vertebral (OAV) spectrum or Goldenhar syndrome is a complex and heterogeneous condition characterized by hemifacial microsomia (unilateral ear abnormalities and ipsilateral mandibular hypoplasia) as well as vertebral anomalies and epibulbar dermoids or lipodermoids. Although most cases of OAV spectrum are sporadic, both autosomal recessive and autosomal dominant inheritance have been reported. Furthermore, the association of OAV spectrum with different types of chromosomal abnormalities has been described. We present a premature newborn delivered after 36 weeks of gestation, whose birth weight was 2,100 g, birth length 43 cm and head circumference 32.5 cm. OAV spectrum with associated axial skeleton anomalies, eventration of the right hemidiaphragm, accessory spleen, unlobulated right lung, agenesis of right kidney, right ovary and right uterine horn, and partial agenesis of corpus callosum were found. She was the second child of unrelated parents, who have a healthy boy. Both parents refused chromosomal analysis of their peripheral blood. Trypsin G-banding and C-banding chromosomal analysis of the patient's peripheral blood revealed a pericentric inversion of chromosome 9 with break points at p11 and q13. This may be a coincidental or causal finding.
