We report the characterisation of a de novo supernumerary
chromosome marker
in a mosaic state (50%) by comparative genomic hybridisation (CGH) in an 8-year-old child with
hypotonia
, dysmorphia and mild-to-moderate mental retardation. We describe the combined use of CGH and fluorescence in situ hybridisation (FISH) to identify the origin of the additional chromosomal material. Visual analysis of 10 CGH-metaphase spreads revealed a gain of green fluorescent signal on pericentromeric region of chromosome 17. The CGH finding was confirmed by FISH analysis using a whole chromosome 17 paint, a chromosome 17 centromeric probe and the probe coding for the Smith-Magenis locus in 17p11.2. These results show that performing both CGH and FISH in combination with classical karyotyping will certainly allow the identification of imbalanced chromosome rearrangements and, by the way, allow the identification of genes involved in mental retardation and/or malformative pathology.
