AHR and neoplasm: PCR amplification of other exons of AHR (2 and 5, chr7:17349286+17349945 and chr7:17369421+17369815, respectively) and a downstream 5’ region of exon 10 (chr7:17379256+17379961, c.1808-intron 10-11) was detected in tumor tissue and germline DNAs, suggesting the presence of a putative variant in the upstream exonic region 10 (Figure 1B).
