IRF8 and laryngotracheoesophageal cleft: Several miRNAs are linked to LC development (miR-22 and miR-142 via the interferon regulatory factor 8 (IRF8), maturation, differentiation (miR-21, miR-34a, miR-99b, miR-223, and miR-511) and the immune function (miR-10, miR-21, miR-142-3p, miR-146a, and miR-155) [150].
