  • Title: Duplication 9q34-->qter identified by chromosome painting.
    Author: Spinner NB, Lucas JN, Poggensee M, Jacquette M, Schneider A.
    Journal: Am J Med Genet; 1993 Mar 01; 45(5):609-13. PubMed ID: 8456834.
    Abstract:
    We have studied an infant with multiple anomalies and a 46,XY,12p+ karyotype. Parental chromosomes were normal, and it was not possible to determine the identity of the extra material on chromosome 12 cytogenetically. Chromosome painting with probes from a chromosome 9 library identified this material as coming from chromosome 9, and cytogenetics established the duplication as 9q34-->qter. Comparison of this patient with others reported with partial dup(9q) documented excellent concordance of minor anomalies, most notably dolichocephaly, "deep-set" eyes, short horizontal palpebral fissures, beaked nose, micrognathia, arachnodactyly, and developmental delay. Identification of cytogenetically indeterminate abnormalities by molecular cytogenetics is very important, as it permits prognosis to be offered for families of newborn infants with unbalanced karyotypes.
