More precisely, there were 4 peptides clones (including 1 in-frame clone; ubiquitin-fold modifier conjugating enzyme 1) with intensity values ≥50 in at least 80% of sera from patients with MG, and 8 peptide clones (including 1 in-frame clone; kinesin family member 18B) with intensity values ≥50 in at least 80% of sera from healthy controls. The gene discussed is UFC1; the disease is myasthenia gravis.
