SLC16A2 and Allan-Herndon-Dudley syndrome: Given that: (1) the zebrafish MCT8 morphant had a similar set of T3-responsive genes to those found in in mice neural derived cells35–37 and human AHDS patients38 and (2) only in zebrafish was the locomotor phenotype typical of AHDS replicated, we propose that the zebrafish MCT8 knockdown model represents a suitable vertebrate experimental model to study human AHDS.
