molecular neuropathology
Branch of neuropathology incorporating genetic and molecular analyses for diagnosis and classification.
Full Definition
Molecular neuropathology represents the integration of traditional morphological examination with molecular techniques including DNA sequencing, gene expression analysis, and protein characterization. This approach has revolutionized brain tumor diagnosis and classification, enabling more precise categorization based on genetic alterations rather than histology alone. The field encompasses mutation analysis, methylation profiling, copy number variation assessment, and protein biomarker studies. These molecular features now form an integral part of diagnostic criteria for many CNS tumors and neurodegenerative diseases.
Usage
Usage note: Distinguished from general molecular pathology by CNS focus.
