MC1R and congenital hypothyroidism: For example, microphthalmia‐associated transcription factor (MITF+/l247s) mutants mimic Waardenburg’s syndrome type II, dual oxidase 2 (DUOX 2D409G/D409G) mutants mimic congenital hypothyroidism, SRY‐box transcription factor 10 (SOX 10+/R109W) mutants mimic Mondini dysplasia, and mutants with a 2 bp CC insertion in the melanocortin receptor 1 (MC1R) mimic albinism.22, 23, 24, 25
