Batten disease. I don&#x27;t mind the question, it&#x27;s been 6 years now, but thanks to my &quot;defenders&quot; ;)<p>Also, my family doesn&#x27;t suffer from it. It is autosomal recessive, so only the unfortunate 1&#x2F;4 have any symptoms at all. My other brother and I are carriers, so we have a 50% chance of passing our gene on to our kids. Neither of our wives are carriers.
