PNPT1 and anemia (phenotype): Colocalization analysis showed pernicious anemia GWAS association colocalises with PNPT1 eQTL signal in thyroid tissue in GTEx v8 dataset (posterior probability for shared causal variant PP4 = 0.87; Fig. 2 and Supplementary Data 1), PNPT1 exon expression QTL in monocytes (PP4 = 0.93–0.96), RP11-554J4.1 eQTL in multiple tissues (PP4 = 0.84–0.92), and CCDC104 exon expression QTL in fat and blood (PP4 = 0.81–0.91).
