Association of Thyroid Peroxidase Antibody with RNF213 p.R4810K Variant in Ischemic Stroke and Transient Ischemic Attack
This multicenter study of 2,090 stroke/TIA patients examined whether elevated thyroid peroxidase antibody (TPO-Ab) levels are associated with the RNF213 p.R4810K genetic variant, known to increase vasculopathy risk. Variant carriers showed significantly higher TPO-Ab levels and increased frequency of elevated antibody titers, suggesting TPO-Ab may act as a second hit in RNF213-related stroke pathogenesis.
