method that is used to learn about all the genes in a
person or in a specific cell type, and the way those genes
interact with each other and with the environment.
Genomic characterization may be used to find
out why some people get certain diseases while others do
not, or why people react in different ways to the same
drug. It may also be used to help develop new ways to
diagnose, treat, and prevent diseases, such as
cancer. Also called genomic profiling.
