title: Molecular cytogenetic studies of duplication 9q32-->q34.3 inserted into 9q13.
abstract: Fluorescence in situ hybridization (FISH) studies using whole chromosome 9 painting probe, classical satellite (9q12-specific) probe and abl cosmid probe (locus: 9q34) were performed on a female infant who was born with multiple congenital anomalies and the karyotype 46,XX, 9q+. The results of FISH confirm the euchromatic nature of the extra material on the long arm of chromosome 9, and provide evidence that it is of chromosome 9 origin. The structural rearrangement has probably resulted from an insertion of a duplicated segment 9q32-->q34.3 into band q13, as shown by the abl cosmid probe. The clinical features in this patient are similar to the previously reported cases of partial trisomy 9q3.
