We report a new case of 8q interstitial duplication in a patient with dysmorphic features, umbilical hernia, cryptorchidism, short stature, congenital heart defect and mild mental retardation (MR). Chromosome analysis with high resolution QFQ bands showed 46,XY, 8q+, which was interpreted as a partial duplication of the distal long arm of chromosome 8 (q22 → qter). This chromosomal aberration was further characterized using fluorescence in situ hybridization (FISH) analyses with multiple DNA probes and array-CGH (Comparative Genomic Hybridization) experiment which demonstrated a de novo direct duplication (8)(q22.2-q24.3). We have compared this case with other partially trisomic 8q patients reported in literature and highlighted the common clinical features in 8q22-8q24 duplication syndrome.
