Test Description

PMC Primary Immunodeficiency Panel examines genes linked to genetic immune system diseases. Genetic testing is crucial for the diagnosis and management of PIDs. Identifying the underlying genetic cause of a patients immunodeficiency can guide treatment decisions, inform prognosis, and facilitate genetic counseling for the patient and their family members.

  • Associated Conditions
    • activated PI3K-delta syndrome
    • agammaglobulinemia and hypogammaglobulinemia
    • Asphyxiating thoracic dysplasia (ATD; Jeune)
    • autoimmune lymphoproliferative syndrome
    • chronic granulomatous disease
    • chronic mucocutaneous candidiasis
    • combined immunodeficiency
  • Methodology

    Targeted Exome/ Slice Exome (Next Generation Sequencing including Copy Number Variation)

  • Limitations

    All sequencing technologies have limitations. A negative result from this analysis does not rule out a possible genetic diagnosis as some variants may not be detected by this test. This test is not designed to detect low level mosaicism, structural rearrangements, indels >40bp, deep intronic variants of unknown clinical significance, or large cytogenetic CNVs. Certain inherent qualities of the human genome, for example repetitive regions/homopolymers, GC rich, pseudogenes, and rare polymorphisms, pose significant technical challenges such as sequence misalignment that may potentially impact the accuracy of the results. False negative results may also occur in the setting of allogeneic bone marrow, stem cell transplantation, active or chronic hematologic conditions, recent blood transfusions, suboptimal DNA quality or PCR trace contamination. Other potential sources of error include sample mix-ups and clerical issues.
