Trisomy 21 alters the development of multiple organ systems, including the face and underlying skeleton. Epigallocatechin-3-gallate (EGCG), a green tea flavonoid, has therapeutic potential for alleviating Down syndrome cognitive impairment and skeletal deficiencies. Here we provide the first evidence showing that EGCG can modulate facial development, with dose-dependent effects. Down syndrome mouse models treated with low doses of EGCG showed improved facial anatomy, whereas high doses of EGCG produced unpredictable facial shape changes, ranging from wild-type to exacerbated trisomic phenotypes. In humans, EGCG supplementation during the first three years of development dramatically reduced facial dysmorphology. Our findings suggest that low doses of EGCG may produce a beneficial effect on facial development of children with Down syndrome, but warn against non-prescribed high dose EGCG intake.
