LP343942-1   MET gene copy number
MET gene amplification studies evaluate the number of copies of the MET gene present in a single cell. Amplification is determined based on the MET gene copy number and MET to centromere ratio. Different criteria have been proposed for what constitutes amplification, including a MET to centromere ratio of >= 2, an average MET gene copy number >=5, and at least 15 gene copies in 10% of the tumor cell nuclei that were counted. MET amplification is associated with worse prognosis in a variety of cancers, including non-small cell lung and gastroesophageal cancer. PMID: 27926778 Source: Regenstrief LOINC

LP343942-1   MET gene copy number
The ratio of MET signals per nucleus to chromosome 7 signals per nucleus is used to determine if MET gene amplification has occurred. MET amplification is a biomarker for different types of cancer, including non-small cell lung cancer. Source: Regenstrief LOINC

LP343944-7   Chromosome 7 copy number
Aneusomy (varying number) of chromosome 7 is evaluated by using a DNA probe that marks the centromeric region of chromosome 7. Such a probe is also called CEP7. The ratio of the number of signals of the MET gene, also on chromosome 7, to the chromosome 7 signal can indicate whether or not there is amplification of the MET gene. Source: Regenstrief LOINC

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.
