My son is 17 and talking daily about joining the service. He is entering his Senior year of high school. Recently we met with a local ROTC representative and this further energized his desire. My fear is that his diagnosis at age 7 of Protein S Deficiency will medically disqualify him. He has never had a clot, is NOT on anticoagulants and requires no restrictions or adjustments to his daily life. I only had him tested because I was a nervous father and needed to know if I passed on this hereditary disorder. His chances of ever having a clot are lower than 3%. Other than the diagnosis, he is a healthy young man. Does the military test for this? I'm assuming he absolutely has to disclose this information...right? Is it waiverable? Thank you for any and all responses.
