Test ID: TACIF    
Transmembrane Activator and CAML Interactor (TACI) Gene, Full Gene Analysis

Secondary ID A test code used for billing and in test definitions created prior to November 2011

84388

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Conditional

Useful For Suggests clinical disorders or settings where the test may be helpful

Evaluating individuals with:

-Common variable immunodeficiency (CVID)

-Clinically symptomatic selective IgA deficiency

-Lymphoproliferative disease associated with CVID

-Autoimmune phenotypes with CVID

 

These clinical features may be consistent with possible TACI mutations, and the genotyping test is especially useful as a follow-up test when flow cytometry is uninformative.

 

Identification of specific TACI mutations in individuals with abnormal TACI flow cytometry results (from IABCS / B-Cell Phenotyping Profile for Immunodeficiency and Immune Competence Assessment, Blood).

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
