Molecular Diagnostics

MD3The Molecular Diagnostics Laboratory provides specialized, high-complexity testing that is not readily available in most hospitals. The laboratory is divided into two areas of specialization:

  • Molecular Genetics provides analysis of DNA variants in the germ line that cause disease or influence the risk of disease.
  • Molecular Oncology provides analysis of mutations that cause cancer.

Services

Our laboratory provides an extensive array of tests and can develop assays for additional disease-associated genetic variants.

Genetics

  • Factor V Leiden mutation: risk factor for developing blood clots
  • Prothrombin (Factor II) 3’UTR (c.*97G>A) mutation: risk factor for developing blood clots
  • Hereditary hemochromatosis (HFE) mutation: risk factor for developing iron overload

Oncology

Clonality Analysis

  • B-cell clonality (IgH gene rearrangement): aids in the diagnosis and monitoring of B-cell lymphoproliferative disorders and in differentiating malignant from reactive lymphoid processes
  • B-cell clonality (IgK gene rearrangement): aids in the diagnosis and monitoring of B-cell lymphoproliferative disorders and in differentiating malignant from reactive lymphoid processes
  • T-cell clonality (TCRG gene rearrangement): aids in the diagnosis of T-cell lymphoproliferative disorders

Single Gene/Fusion Transcript Analysis

  • BCR-ABL1 (p210) analysis by quantitative PCR: diagnosis and monitoring of chronic myeloid leukemia (CML) and a subset of acute lymphoblastic leukemia (ALL) 
  • BRAF V600 and NRAS hotspot mutation (Idylla): diagnostic and predictive biomarker for several cancers, including cutaneous melanoma
  • CALR mutation (by PCR): aids in the diagnosis of JAK2-negative essential thrombocytosis and primary myelofibrosis
  • EGFR mutation (Idylla): predictive biomarker for targeted therapy in non-small cell lung cancer
  • FLT3 internal tandem duplication (ITD) mutation: prognostic and predictive biomarker for targeted therapy in acute myeloid leukemia
  • FLT3 codon 835/836 mutation: predictive biomarker for targeted therapy in acute myeloid leukemia
  • JAK2 V617F mutation (by allele-specific PCR): aids in the diagnosis of myeloproliferative neoplasms
  • KRAS mutation (Idylla): predictive biomarker for targeted therapy in non-small cell lung cancer and colorectal cancer

Targeted Next Generation Sequencing (NGS) Panels

Other Tests

  • Bone marrow transplant (BMT) engraftment analysis: detects genetic differences between recipient and donor prior to BMT; monitoring bone marrow engraftment status after BMT
  • Microsatellite instability analysis (Idylla): screening for hereditary nonpolyposis colorectal cancer (Lynch syndrome); predictive biomarker for immunotherapy in solid tumors
