From: Discrepancy of QF-PCR, CMA and karyotyping on a de novo case of mosaic isodicentric Y chromosomes
Karyotyping and FISH analysis of cultured amniotic cells. Karyotyping indicated a mosaic of 45,X and 45,X plus an derivative chromosome (a). FISH (b) was performed using Alpha Satellite DNA probe located in Xp11.1-q11.1 and Yp11.1-q11.1 (AneuVysion Multicolor DNA Probe Kit, Abbott, USA).The data revealed the derivative chromosome was composed of two Y chromosome centromeres (arrow)
