A 27-year-old male asked:

I have positive anti etar antibodies could this be causing my dysautonomia symptoms with faulty vasoconstriction?

Possibly but: The ETAR assay is designed to detect antibodies that form against endothelin receptor type A (anti-ETAR), a G protein-coupled receptor. anti-ETAR antibodies can be useful to evaluate the risk of allograft loss. It is not apparent that it is related to dysautonomia.
