About this work
Description
Human chromosome highlighted by fluorescent probes
that bind to specific sequences of DNA. In this
FISH (fluorescence in situ hybridisation) study a
probe (red) from the Prader Willi and Angelman's
syndromes critical region (PSASCR) and a
chromosome 15 centromere specific probe (green)
show that the 15q.11>q13 duplication does not
include the PWASCR.
