Test ID: BCLGP    
B-Cell Deficiency Primary Immunodeficiency (PID) Gene Panel

Providing a comprehensive genetic evaluation for patients with a personal or family history suggestive of primary B-cell deficiencies and related disorders

Patients with B cell immunodeficiencies who may have other clinical presentations, besides the humoral immune defect, such as inflammatory bowel disease, autoimmunity, or other as indicated above

Establishing a diagnosis of a B-cell deficiency or related disorder, in some cases, allowing for appropriate management and surveillance for disease features based on the gene involved

Identifying variants within genes known to be associated with increased risk for disease features allowing for predictive testing of at-risk family members

This test includes next-generation sequencing and supplemental Sanger sequencing to evaluate for the genes listed on the panel.

The PMS2 gene will be performed on whole blood or DNA submitted samples only at an additional charge via Sanger Sequencing and MLPA when clinical history of defective immunoglobulin class switching is provided.

Due to lower concentration of DNA yielded from alternate specimen sources, _PMS2 cannot be performed on any sample type other than whole blood or DNA extracted from whole blood.

For skin biopsy or cultured fibroblast specimens, fibroblast culture and cryopreservation testing will be performed at an additional charge. If viable cells are not obtained, the client will be notified.
