Does a negative attr gene test mean i have wild type?
thanks, Sheldon. I was waiting for your answer… Yes, I had a negative AL test so I’m assuming wild type. Continued prayers for everyone.
Genetic testing for hereditary ATTR otherwise known as hATTR or vATTR, that yields a negative result for all 130 genome responsible for hATTR, may mean that you either have wtATTR or AL Amyloidosis. A Kappa/Lamda blood test and a 24-hour urine test for light proteins can rule out AL Amyloidosis. Then you know with certainty that you have wtATTR.
I have biopsy-proven Cardiac AL. Urine has always been negative, as was fat-pad (abdominal) aspirate.
A negative ATTR gene test does not automatically mean you have wild-type ATTR amyloidosis. Here's a detailed explanation:
- Testing Process
- If a protein sequence analysis test on a biopsy sample shows that the TTR protein is involved, a blood sample is sent for a genetic-sequencing test to examine the DNA chains.

love it!!! stay wild
TTR and Lambda per mass spec. Did not differentiate between systemic or localized, nor between wild / mutant ocular amyloidosis. Now what?
What test do i need to find out if my attr-cm is wild or hereditery?
What should I know following a PYP scan positive for ATTR-CM? Need for biopsy? Hereditary vs wild type? Treatment/monitoring for family?
