Abstract
A boy with a duplication 12q24 to qter shows the characteristic phenotype of this chromosome abnormality. The aberration could be analysed as an unbalanced translocation 12/14 de novo by combining different banding techniques with FISH and SKY. Heterologous euchromatin translocations on the heterochromatic short arm regions of the acrocentrics are an extremely rare type of rearrangement.
