CTLA4 and type 1 diabetes mellitus: When training our T1D regularised logistic regression predictors, we identified a split distribution for the lung that was dependent upon the lasso regularisation inclusion or exclusion of the rs3087243-CTLA4 cis-acting (i.e. <1 Mb apart) spatial eQTL within the two tissues where it was identified (i.e. lung or testes; Supplementary Fig. 4).
