VGKC blood test

Hi - has anyone had a voltage gated potassium channel (vgkc) antibody test? I’ve had this twice this year, both times it’s come out positive. Although at the time of the first one I’d two evoked potential (Visual EP, and Transcranial Motor EP) which didn’t show anomaly.

Does anyone know of association of vgkc with MS, or otherwise? I’ve had loads of other blood work, which has shown nothing.
