Hematology Profile Plus

GTC-Hematology Profile Plus combines expression and fusion with mutation analysis in DNA and RNA. The test covers 284 DNA genes and more than 1600 RNA genes. This is a comprehensive evaluation for all hematologic neoplasms. However, it is especially recommended for:

Acute Myeloid Leukemia (AML): Translocations in AML are very important for diagnosis, prognosis and therapy selection. This comprehensive test can provide a complete evaluation of fusion mRNA and mutations. It also helps in determining a diagnosis in acute leukemia with ambiguous phenotype.

Clonal Hematopoiesis of Indeterminate Potential (CHIP): Distinguish CHIP from clinically active and relevant hematologic neoplasm based on an internally developed algorithm using variant allele frequency, chromosomal structural abnormalities, clinical and laboratory data and longitudinal data. This distinction is particularly important when evaluating minimal residual disease and in the presence of other neoplastic processes.

VEXAS Syndrome: Recently described VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) is caused by mutations in the UBA1 gene. This is an adults-onset fatal disease that may present as myelodysplastic syndrome, aplastic anemia or multiple myeloma, but is also characterized by fevers, low white cell count, vacuoles in bone marrow cells, dysplastic bone marrow, pulmonary inflammation, chondritis, and vasculitis. Detecting the presence of mutations in the UBA1 gene is the only way to confirm the diagnosis of this syndrome.

Acute Lymphoblastic Leukemia (ALL): This comprehensive assay is designed to confirm the diagnosis of Ph+ (BCR::ABL1-positive) ALL and Ph-like (BCR::ABL1-like) ALL and distinguish them from other types of ALL. It can be used for diagnosis as well as for monitoring. The incidence of Ph-like ALL is 20% to 25% of adult ALL and 15% of pediatric ALL. Diagnosis of Ph+-ALL and Ph-like ALL is very important because TKI therapy can be helpful in most of these patients. This assay can determine most of the mutations, translocations, and expression of genes (CRLF2) associated with Ph+ ALL and Ph-like ALL.

Diffuse Large B-cell Lymphoma (DLBCL) and Other Types of Lymphoma or Plasma Cell Neoplasms: This assay can provide very valuable information for the management and monitoring of patients with DLBCL. It can distinguish between activated B-cell-like (ABC) and germinal center B-cell-like (GCB) and can help in the diagnosis of double hit lymphoma. The assay is also useful for other types of lymphoma, including follicular lymphoma and T-cell neoplasms, as well as multiple myeloma.

IgVH Mutation Status: Very important for prognosis and therapy selection in patients with chronic lymphocytic leukemia (CLL).

T-cell and B-cell Clonality Detection: The detection of T- and B-cell clonality is important because it can help diagnose and monitor certain types of malignancies. When a malignant transformation occurs in a T- or B-cell, the cells can undergo uncontrolled clonal expansion, resulting in the accumulation of a large number of identical cells with the same T- or B-cell receptor.

Epstein-Barr Virus (EBV): Important for diagnosis and classification of lymphoproliferative neoplasms.

Torque Teno Virus (TTV): This virus was first discovered in a patient with non-A-E hepatitis and is now regarded as a part of the human virome. In general, TTV does not cause pathology in immunocompetent individuals. This virus is considered as a marker of the degree of immune competence in patients with immunological impairment and inflammatory disorders. High TTV load is associated with increased risk of infection. In patients with organ transplant, low TTV load is associated with an increased risk of rejection.

Other Features of Hematology Profile Plus:
- HLA class I genotyping
-Enrichment for CD138-positive plasma cells is performed on bone marrow specimens with the clinical indication of multiple myeloma
-A preliminary report will be issued for any patient positive for FLT3-ITD by fragment analysis or with a clinical indication of acute leukemia

Turn Around Time: 7-10 Days

GTC uses AI in every step of our analysis and it makes a difference in helping make a new discovery daily that improves patient care.

Once the data is offloaded from the sequencer, our AI:

  1. Assists with mutation analysis, identifying non-mutations and artifacts
  2. Compares various data sets to explore disease biology
  3. Provides support for clinical decision-making and classification of the disease
  4. It helps with matching patients to therapeutics and presents clinical trial options
  5. Aggregates data for report generation and simplifies the results so they are easily understood

Case Study: VEXAS Syndrome


VEXAS syndrome is a disease with inflammatory and hematologic (blood) manifestations. The syndrome is caused by mutations in the UBA1 gene affecting the Met41 residue of the protein and resulting in decreased cellular ubiquitylation activity and hyperinflammation. This is an adults-onset fatal disease that may present as myelodysplastic syndrome, aplastic anemia or multiple myeloma, but characterized by fevers, low white cell count, vacuoles in bone marrow cells, dysplastic bone marrow, pulmonary inflammation, chondritis, and vasculitis. Detecting UAB1 gene mutations in the is the only way for confirming the diagnosis of this disease.

Clinical History

68-year-old male
With low-grade myelodysplastic syndrome and inflammatory manifestations including arthritis, chondritis or other autoimmune disorders
Molecular Profiling Findings
Mutations in UBA1, DNMT3A, and TET2 genes


The presence of DNMT3A, and TET2 suggest early low-grade myelodysplastic syndrome (MDS). And the detection of UBA1 mutation along with the patient’s symptoms confirmed the diagnosis of VEXAS. This patient was undiagnosed for long period of time and became transfusion dependent. By using any of our hematology DNA, DNA+RNA or cfDNA NGS panels; we are able to accurately diagnose VEXAS syndrome. This patient and most of the patients who are currently diagnosed with VEXAS have had numerous tests and tried multiple treatments. VEXAS should be considered in patients with systemic autoinflammatory disorders as well as patients with clinical presentation of myelodysplastic syndrome.
