Autoantibodies against eukaryotic translation elongation factor 1 delta in two patients with autoimmune cerebellar ataxia.

Background: Autoantibodies are useful biomarkers for the early detection and diagnosis of autoimmune cerebellar ataxia (ACA).

Objective: To identify novel autoantibody candidates in ACA patients.

Methods: Patients with cerebellar ataxia of unknown cause were recruited from July 2018 to February 2023.
