Extended Data Fig. 1. Whole-cortex (vertex-wise) comparison of RELN-COLBOS carrier to typical MCI PSEN1 E280A carriers’ tau PET.
This analysis confirmed that compared to other PSEN1 E280A carriers who developed MCI at younger ages, the RELN-COLBOS carrier had relatively spared tau PET signal in the medial temporal lobe (entorhinal cortex / parahippocampal gyrus), but not in other areas including temporal neocortex. a, Cortical surface projection of vertex-wise tau PET (Flortaucipir, FTP) standardized uptake value ratio (SUVr) in the RELN-COLBOS carrier. b, Mean tau PET image of typical MCI PSEN1 E280A carriers (n = 7). c, difference analysis between images (b) and (a): negative values indicate areas where RELN-COLBOS carrier had higher tau PET signal compared to other carriers, and vice-versa. d, T-value for one-sample 2-sided t-tests comparing other PSEN1 E280A carriers to the RELN-COLBOS patient. Directionality of effect size is the same as (c). Panel e shows T-values as in (d) masked by p value < 0.05 (uncorrected). f, Inferior / close-up view of surfaces shown in (e).
