Rare variant may lead immune system to attack healthy cells, study finds

The research is focused on mutations in the gene coding an enzyme in charge of a crucial cell in the immune system. The enzyme, called sialic acid acetylesterase, controls the immune system's B cells -- white cells that produce antibodies to fight the foreign proteins of viruses, bacteria and other invaders. If the enzyme fails to rein in the B cells, they may attack the body's healthy cells by mistake.
