Partial trisomy 11q syndrome (11q23.1-->11qter) due to de novo t (11q; 13q) detected by multicolor fluorescence in situ hybridisation.

In this report we describe the identification of a de novo 46, XX, 13q + by multicolour fluorescence in situ hybridisation (M-FISH), as a partial distal 11q trisomy (11q23.1-->11qter). The clinical phenotype association with this distal 11q trisomy is briefly reviewed.
