Phenotype resembling Donnai-Barrow syndrome in a patient with 9qter;16qter unbalanced translocation.
We describe a 3-year-old boy with complete agenesis of corpus callosum, developmental delay/mental retardation, anterior diaphragmatic hernia, Morgagni type, severe hypermetropia, and facial dysmorphism suggesting the diagnosis of Donnai-Barrow syndrome. Subtelomeric FISH analysis revealed a paternally-derived t(9;16) (q34.3;q24.3) translocation with partial 9q monosomy and partial 16q trisomy. As some facial features resemble the 9q emerging phenotype, we suggest the hypothesis that some patients with Donnai-Barrow syndrome might be abscribed to 9q terminal deletion.
