Molecular Diagnosis

The molecular diagnosis laboratory is directed by Dr. James Zehnder. We perform gene rearrangement studies for T- and B-cell clonality by PCR, tests for microsattelite instability and PCR or FISH for chromosomal translocations. To submit directly to the molecular laboratory, please download the Molecular Genetic Requisition Form

We can also test for microsatellite instability for the Muir Torre or Lynch syndromes via PCR analysis (as an adjunct to immunohistochemical studies). Our laboratory (650-498-7396) can be contacted directly for further information.

Fluorescence in situ hybridization (FISH) studies for chromosomal translocations and rearrangements that are associated with particular types of leukemias/lymphomas and solid tumors are performed in the Cytogenetics Laboratory.  The Cytogenetics Laboratory is directed by Dr. Athena Cherry.
