The extracted data demonstrated congruent DRD (except DRD3 mRNA) genes and TAAR1 gene expression in different datasets, representing the expression patterns in duodenal samples from healthy subjects (GSE151495, GSE169034, GSE189820, and GSE207243) and non-affected duodenal samples from patients with familial adenomatous polyposis (GSE94919, GSE189035, Figure 2a,b). This evidence concerns the gene DRD3 and Familial adenomatous polyposis.
