RAG2 Gene Combined Immunodeficiency B Cell-Negative T Cell-Negative NK Cell Positive NGS Genetic DNA Test
Comprehensive Introduction to RAG2 Gene Immunodeficiency Testing
The RAG2 Gene Combined Immunodeficiency NGS Genetic DNA Test represents a breakthrough in molecular diagnostics for severe immune system disorders. This advanced genetic screening utilizes next-generation sequencing technology to identify mutations in the RAG2 (Recombination Activating Gene 2) that are responsible for combined immunodeficiency conditions characterized by absent B cells and T cells with preserved natural killer (NK) cell function.
RAG2 plays a critical role in V(D)J recombination, the process that generates diverse antigen receptors essential for adaptive immunity. Mutations in this gene disrupt normal immune cell development, leading to severe combined immunodeficiency (SCID) with distinct cellular patterns. Early detection through this specialized test can be life-saving, as it enables prompt intervention before devastating infections occur.
What This Advanced Genetic Test Measures and Detects
Our comprehensive NGS-based analysis specifically targets:
- Complete sequencing of the RAG2 gene coding regions
- Detection of point mutations, insertions, and deletions
- Identification of splice site variants affecting gene function
- Assessment of genetic variants associated with B cell-negative, T cell-negative, NK cell positive SCID
- Comprehensive variant analysis with clinical correlation
The test employs state-of-the-art next-generation sequencing technology that provides unparalleled accuracy in detecting even rare genetic variants that conventional methods might miss. This high-resolution approach ensures comprehensive coverage of the RAG2 gene, delivering reliable results for clinical decision-making.
Who Should Consider RAG2 Gene Testing
Clinical Indications and Symptoms
This specialized genetic test is recommended for individuals presenting with:
- Recurrent, severe, or unusual infections in infancy or early childhood
- Failure to thrive and persistent diarrhea
- Family history of severe combined immunodeficiency
- Unexplained opportunistic infections
- Abnormal lymphocyte counts with absent B and T cells
- Persistent candidiasis or other fungal infections
- Poor response to routine vaccinations
- Consanguineous parentage with suspected autosomal recessive inheritance
At-Risk Populations
Healthcare providers should consider testing for patients with clinical features suggestive of SCID, particularly those with the characteristic immunophenotype of absent B and T lymphocytes with preserved NK cells. Early diagnosis is crucial for considering hematopoietic stem cell transplantation, which offers the best chance for survival.
Significant Benefits of RAG2 Gene Testing
Undergoing this comprehensive genetic analysis provides multiple advantages:
- Accurate Diagnosis: Precise identification of RAG2 mutations confirms the specific genetic cause of immunodeficiency
- Treatment Guidance: Results inform decisions about hematopoietic stem cell transplantation and other therapies
- Family Planning: Enables genetic counseling and carrier testing for family members
- Early Intervention: Facilitates prompt treatment before life-threatening infections develop
- Prognostic Information: Helps predict disease severity and potential complications
- Personalized Medicine: Supports tailored treatment approaches based on specific genetic findings
Understanding Your Test Results
Our comprehensive genetic report provides detailed interpretation of your RAG2 gene analysis:
Possible Result Interpretations
- Pathogenic Variants Detected: Confirms diagnosis of RAG2 deficiency with appropriate genetic counseling recommendations
- Likely Pathogenic Variants: Strong evidence supporting disease causation with clinical correlation needed
- Variants of Uncertain Significance: Requires additional family studies and functional analysis
- No Pathogenic Variants Detected: Does not completely rule out RAG2 deficiency; clinical correlation essential
Clinical Implications
Positive results typically indicate autosomal recessive inheritance, meaning both parents are carriers. This information is crucial for genetic counseling and family planning. Negative results in symptomatic patients may warrant additional genetic testing for other SCID-related genes.
