Anyone been told anything about low IgA subclass 1?

My son is low IgA, subclass 1, and lower end of normal range for subclass 2. What have you been told by your docs, if your child has low IgA??

We didn't run the subclasses for IgA. But my daughters total IgA is very low. You have to be careful w/ IVIG if you have low IgA because you're more prone to reactions. We do IVIG that is low in IgA. Not from the doc, but the only real significance I've seen in the literature is that low IgA makes one prone to autoimmune disease. Have not found a lot of info on it at all.
