Abstract
We describe a 7-year-old patient with pervasive developmental disorder and behavioral problems who has a de novo cryptic unbalanced der(2)t(2;16)(p25. 3;q24.3) chromosome resulting in deletion of distal 2p and duplication of distal 16q. These segmental aneusomies were detected by microarray comparative genomic hybridization analysis, as was a distal 17p13.3 duplication that was inherited from her father. FISH analysis using bacterial artificial chromosomes confirmed a deletion of approximately 1,700 kbp of DNA from 2pter (containing at least six complete genes or transcription units) and a duplication of ∼500 kbp from 16qter (including up to ten genes or transcription units). Several genes in these regions are plausible candidates for contributing to the patient's phenotype.
