FISH FOR CRI-DU-CHAT SYNDROME OR 5P DELETION

Description

Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique used to diagnose Cri-du-chat syndrome (also known as 5p- syndrome or 5p deletion syndrome). It helps identify deletions on the short arm of chromosome 5 (5p). This technique uses fluorescently labeled DNA probes that bind to specific regions of chromosomes, allowing visualization of deletions or other chromosomal abnormalities.
