General Description
GAD-Ab, or Glutamic Acid Decarboxylase Autoantibodies, are antibodies that target the glutamic acid decarboxylase (GAD) enzyme, which is crucial for producing GABA, an inhibitory neurotransmitter. These antibodies are associated with several autoimmune conditions, most notably Stiff Person Syndrome (SPS) and Type 1 Diabetes (T1D). Testing for GAD-Ab can help in the prediction, diagnosis, and management of these conditions, although their correlation with disease severity or therapeutic response is not always clear. Two vertebrate genes, GAD1 and GAD2, encode distinct GAD proteins: GAD67 and GAD65. GAD1 and GAD2 sequences are highly similar to each other, and they share a common intron-exon organization, indicating a common origin.
