My husband is Vietnam veteran. He has been diagnosed with TTR amyloidosis. His genetic test proves he did not inherit it. Can he get disability from the VA for his condition?
It's questionable whether VA will allow whatever genetic test you have as evidence enough to sway their opinion. This is a good example of just how complex these cases can become...https://www.va.gov/vetapp16/Files5/1636648.txt
However, were I you I'd apply for benefits and argue my case because if you don't, you'll never know. Every claim and every decision is different and the only way to be sure is to formally file the claim. Good luck.
