Term Description

This test determines if chromosome 1 polysomy is present in tissue (tumor) specimens. Chromosome 1 polysomy is defined as 3 or more signals for 1q and/or 19p in >30% of tumor cells with concurrent 1p/19q deletion. PMID: 19808867 Chromosome 1 polysomy is a prognostic indicator of poorer outcome for oligodendroglioma patients.

Part Description

LP62864-1   FISH
FISH (fluorescence in situ hybridization) is a cytogenetic technique used to detect and localize the presence or absence of specific DNA sequences on chromosomes. FISH uses fluorescent probes that bind to only those parts of the chromosome with which they show a high degree of sequence similarity. Fluorescence microscopy can be used to find out where the fluorescent probe bound to the chromosomes. FISH is often used for finding specific features in DNA for use in genetic counseling, medicine, and species identification. FISH can also be used to detect and localize specific mRNAs within tissue samples. In this context, it can help define the spatial-temporal patterns of gene expression within cells and tissues.
