Abstract
We report on a 5-year-old Tunisian boy with particular dysmorphic features and mild mental retardation limited in delayed and poor language acquisition. Cytogenetic analysis using RHG banding and FISH using whole chromosome four painting probe showed a partial duplication in the long arm of chromosome four. Locus specific probes and CGH confirmed the presence of a ‘‘pure’’ partial trisomy 4q due to de novo direct tandem dup(4)(q25q34). Comparative analysis of our case with those published previously, suggests that region 4q31–q33 may be involved in the development of the 4q characteristic dysmorphic features and the distal band 4q35 may be involved in the development of microcephaly and severe mental and growth retardation.
