KLC1 and temporal arteritis: On the other hand, anti-KIF4A (aa 376–461) showed significantly higher prevalence in AAV and anti-KLC1 (aa 487–550) in AAV, GCA, and PMR, while anti-KIF3A (aa 376–461) and anti-KIF12 (aa 430–513) were both more prevalent in patients with PMR compared to GCA and other groups (Supplementary Figure S5 and Figure 2).
