Anticentromere B Antibody

Has anyone tested positive for CENP-B? I tested positive a few months ago and now have developed Raynaud’s in one single toe when I’m stressed (along with other symptoms that aren’t relevant in this sub).

The rheumatologist blew me off (what a surprise). My reading says that CENP-B is very rare in healthy people, but can occur in primary Raynaud’s.
