NCIt definition : The identification of genetic variation in a biological sample.;
Alternative definition : NCI-GLOSS: Germline genetic testing method targeted to detect a specific mutation
(such as a deleterious MSH2 mutation previously identified in a family), panel of
mutations (such as the 3 BRCA mutations comprising the founder mutation panel for
individuals of Ashkenazi Jewish ancestry) or type of mutation (such as a large deletions
or insertions in the BRCA1 gene). This type of testing is distinct from complete gene
sequencing or mutation scanning. The latter are designed to detect most mutations
in the region being tested. Current usage also applies this term to any genetic test.;
