@matthew2001, please remember that there are multiple genetic issues which can cause this, as well. I have a few, so I know it would be important to have a lab (Apollo, Sequencing, Nebular, etc.) do a full genome workup. It costs a few hundred, but is much less expensive than going through life trying to nit-pick your way across the ocean without a rudder. Most of these now are done with either a spit sample or blood sample. Very easy. Fine a good geneticist to help you, if you have questions.
