Figure 2From: Spectral Karyotyping for identification of constitutional chromosomal abnormalities at a national reference laboratoryA supernumerary bisatellited marker originating from chromosome 22 detected in a peripheral blood sample from a 2-year-old boy. Banded metaphase (left) and spectral karyotype (right) are shown. Marker origin was confirmed by FISH using probes for 14/22 centromeres and the TUPLE1 gene locus (22q11.2) (not shown).Back to article page
