FISH diagnosis of partial trisomy 13 and tetrasomy 13 in a patient with severe trigonocephaly (C) phenotype.
An infant girl with manifestations resembling Optiz trigonocephaly (C) syndrome who died at age 6 days was found to have a complex chromosome abnormality with t(13;18)(q22;q23) and a recombinant chromosome 13 involving duplicated segments of 13q. Precise characterization was possible with the application of fluorescence in situ hybridization (FISH) using chromosome specific probes. The patient's phenotype is compared to that of other syndromes involving trigonocephaly.
