OverviewNCBI Gene
The protein encoded by this gene is an enzyme that catalyzes the transfer of a sulfate group to the GlcNAc residues of keratan. Keratan sulfate helps maintain corneal transparency. Defects in this gene are a cause of macular corneal dystrophy (MCD). [provided by RefSeq, Jan 2010]

Whether an antibody against CHST6 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads CHST6 as an antibody target. Whether an autoantibody or antibody against CHST6 could matter depends on whether native CHST6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
CHST6 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label CHST6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
