It was found that DICER1 rs3742330 AG heterozygote is connected with LC Stages III and IV (OR: 2.3243, 0.95 CI: 1.0828–4.9893, and p = 0.0276 [pcorr = 0.248] and OR: 2.9971, 0.95 CI: 1.4173–6.3378, and p = 0.0031 [pcorr = 0.028], resp., Table 5(b)) and DICER1 rs13078 TT genotype is associated with LC Stage III (OR: 9.1667, 0.95 CI: 1.1122–75.5513, and p = 0.01450 [pcorr = 0.131], Table 5(b)). This evidence concerns the gene DICER1 and laryngotracheoesophageal cleft.
