Interestingly, by analyzing human genome‐wide association study (GWAS) data obtained from the UK Biobank (Figure S3A, Supporting Information), we found a significant correlation (p = 9.39 × 10−5) between an intergenic mutation located between the RD3 and SLC30A1 genes on chromosome 1 (n.211740959 C > T; Figure S3B, Supporting Information) and Crohn's disease in male patients (based on 471 cases and 16,6517 controls). Here, RD3 is linked to Crohn disease.
