Lipoprotein A

Has anyone ever heard anything about elevated lipoprotein A? Read something that elevated lipoprotein A helps contribute to EM. My son has Em really bad. He has never been tested for this but I do know that I have elevated lipoprotein A. I know that you can take an injection called repatha to bring the levels down wonder if you have elevated lipoprotein A and bring it down the symptoms of EM could be less severe.
