  • Title: Unbalanced mosaic karyotypes with different structural abnormalities involving a common chromosome region: report of two cases.
    Author: Pettenati MJ, Teot LA, Smith C, Hayworth R, Thomas IT, Veille JC, Rao PN.
    Journal: Am J Med Genet; 1993 Feb 01; 45(3):365-9. PubMed ID: 8434625.
    Abstract:
    We report on 2 cases with different de novo unbalanced mosaic karyotypes in which each cell line had a different structural abnormality involving a common chromosome region: 46,XX,del(11)(q23.3)/46,XX.-11, + der(11)t(11;?)(q23.3;?) and 46,X,idic(Xq)/46,X,idic(Xq),-12, + der(12)t(X;12)(p11.2;p13.3). Molecular-cytogenetic analysis confirmed the origin of the derivative 12 chromosome in the latter. We present a literature review of reports with mosaic cell lines of structural chromosome abnormalities that share the same chromosome breakpoint.
