FDA approved Normal/Abnormal determination cutoff. Summary: NORMAL CLL FISH PANEL RESULTS Final Interpretation: This FISH analysis showed normal signal patterns for 11q22.3/17p13, CEP12/13q14/13q34, 11q13/14q32, and CEP6/6q23 probes listed above in the CLL panel.

FISH analysis can only identify abnormalities that are within the specific locus of the probe(s) used and may not detect small clonal populations of aberrant cells below the normal cut-off values; therefore, FISH results should be interpreted in the context of the patient s full clinical history and under most circumstances, in conjunction with metaphase chromosome analysis. D Pal Singh-Kahlon, PhD, FACMG, Director of Cytogenetics Date: 01/24/2012 FISH testing for HER2/neu (PathVysion), ALK for Non Small Cell Lung Cancer (NSCLC), MDS (for EGR1 (5q31)/5p15.2 probe), CLL (for TP53, ATM probes, D13S319 and D12Z3 probes), and X/Y probes for bone marrow (BM) transplant monitoring, have been approved by Food & Drug Administration (FDA) as in vitro diagnostic (IVD) tests. However, some other probes in use for MDS & CLL FISH tests are Analyte Specific Reagents (ASRs). In MDS, 7cen/7q31, cep8, 20q12, and MLL (11q23) probes are ASRs. In CLL c-myb(6q23), CCND1/IGH( t(11;14)) are ASRs. The tests utilizing analyte-specific reagents (ASRs) were developed & their performance characteristics determined by Cancer Genetics, Inc. as required by CLIA 88 regulations. They have not been cleared or approved by for specific uses by the Food and Drug Administration (FDA). The FDA has determined that such clearance or approval is not necessary. These tests are used for clinical purposes. Cancer Genetics Inc., 201, Route 17 North, Rutherford, NJ Phone Number : (888) CLIA#: 31D CAP LAP#: Giumara, Ross J. FH Page 2 of 2

5 Reported: 01/28/2012 Clinical Hx: Lymphoma Results: IGHV Family: V3-30 Functionality: CGI ID No: Client: Client Address: IGHV MUTATION ANALYSIS REPORT Mutation Frequency: 2.1% Productive Interpretation: Mutated (borderline mutated, see comment below) Comment: Patients with borderline IGHV mutation (close to 2% cut-off) have varying clinical outcome. Caution should be taken when interpreting clinical correlation. Description: The mutation status of the unique immunoglobulin gene (IGHV) rearrangement in the monoclonal proliferation of B-cells in chronic lymphocytic leukemia (CLL) is considered to have prognostic value. If mutations are detected at a level of 2% or higher in the sequenced V region of the clonal rearrangement, then the result is interpreted as Mutated. If mutations are detected at a level below 2% in the sequenced V region of the clonal rearrangement, then the result is interpreted as Unmutated. Those patients with a mutated IGHV gene usually have a less aggressive and more indolent disease, with longer overall survival. Those patients with an unmutated IGHV gene usually have a more aggressive disease and shorter overall survival. This assay utilizes PCR to detect a monoclonal IGHV rearrangement followed by sequence analysis to determine the specific IGHV family and mutation frequency. The sensitivity of the assay is 10%. Samples in which the monoclonal B-cells are present at less than 10%, a specific IGHV rearrangement will not be detected and will be reported as failures.

Description: The gain and loss of specific genomic regions in the monoclonal proliferation of B-cells in chronic lymphocytic leukemia (CLL) are considered to have diagnostic and prognostic value. Loss of 13q at one locus (MIR15A/16-1) or both loci (MIR15A/16-1 and RB1) is observed in approximately 50% of CLL patients and as the sole abnormality is associated with a longer overall survival. Those patients with loss of 17p (TP53) or 11q (ATM) in general, have a shorter overall survival. Other aberrations are variously observed in CLL patients with suggested prognostic value. This assay utilizes microarray-based comparative genomic hybridization (array-cgh) to simultaneously detect the gain and loss of multiple loci in specimen DNA. Quantitative PCR is used to confirm the detected genomic gains and losses. The sensitivity of the assay is 30-40%. Samples in which the monoclonal B-cells are present at less than 30-40%, aberrations may not be detected and will be reported as no aberrations detected.
