I recently was reading the testimony of a person with "Undifferentiated Connective Tissue Disease". I had to look that up. A persons' own antibodies attack the connective tissue at joints resulting in Rheumatoid Arthritis. Sound familiar. I realize this is not strictly an Alpha 1 group, however, we are all under this umbrella. Since antitrypsin protein also protects body parts other than the lungs, Is it possible that Antitrypsin protein deficiency could also be related to UCTD?
