FISH FOR DELETION OF SNRPN REGION

Description

Fluorescence in situ hybridization (FISH) can be used to detect deletions of the SNRPN region, particularly in cases of Prader-Willi syndrome (PWS). This test utilizes fluorescently labeled DNA probes that bind to specific sequences within the SNRPN gene region on chromosome 15, allowing for visualization of deletions under a microscope.
