title: Partial duplication of 3q (q25.1-->q26.1) without the Brachmann-de Lange phenotype.
abstract: Partial duplications of chromosome 3 have previously been reported to have phenotypic characteristics similar to Brachmann-de Lange syndrome (BDLS). We present the case of a 13-year-old girl with an apparent duplication in the 3q25.1-->q26.1 region but none of the manifestations commonly seen in BDLS. The chromosome 3 duplication was confirmed with a FISH painting probe of the involved region. These results suggest that the region critical for Brachmann-de Lange syndrome is not within the duplicated region of 3q25.1-->q26.1.
