Invitae Common Variable Immunodeficiency Panel
Use
The Invitae Common Variable Immunodeficiency Panel analyzes genes associated with common variable immunodeficiency (CVID), characterized by hypogammaglobulinemia, poor antibody response to vaccines, recurrent infections, inflammatory disorders or autoimmunity, and increased risk for malignancy. This panel provides a broad evaluation for CVID, which is genetically heterogeneous, allowing assessment of many potentially relevant genes based on a single clinical indication. CVID presents with decreased serum IgG levels, often alongside decreased IgA and/or IgM, leading to increased susceptibility to infections and potential development of autoimmune diseases and malignancies.

Limitations
The panel uses next-generation sequencing (NGS) with high sensitivity for detecting single nucleotide variants and deletions/duplications. However, certain types of variants and structural rearrangements may not be detected due to sequencing limitations. The assay covers coding exons and adjacent intronic regions but does not guarantee detection in non-coding regions or for structural rearrangements. Additionally, in rare cases involving hematolymphoid neoplasms or recent transplants, the analyzed DNA may not reflect the patient's constitutional genome.
