Microdeletion/microduplication FISH
Overview
The investigation of microdeletion and microduplication syndromes is now performed by microarray analysis. Microarray provides a superior investigation than FISH testing as it detect a wider range of genetic changes that may cause each syndrome. If an urgent investigation is required, FISH can be performed in 24-48 hours (see Notes)
