SKOR2 autoantibodies may serve as a marker of a cytotoxic T-cell–mediated injury directed through T-cell receptors recognizing SKOR2 peptides, similar to PCA1 or KLHL11 autoantibody-associated paraneoplastic cerebellar degeneration (12, 42). The gene discussed is SKOR2; the disease is paraneoplastic cerebellar degeneration.
