FISH, Chromosome D13S319, Del 13q14.3
Clinical Use
Order TestUse
This fluorescence in situ hybridization (FISH) assay detects deletions in chromosome 13q14.3 with a probe specific for the D13S319 locus. The results of this test may aid in the prognostic assessment for chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). At least one of the common genetic abnormalities of CLL/SLL—del(13q), del(11q), trisomy 12, or del(17p)—can be detected with FISH in over 80% of patients with CLL/SLL. Evaluation of these frequent genetic abnormalities is recommended for prognostic investigation and may inform treatment decisions.
