Milly Shapiro’s Tiktok Surge Rekindles Gaten Matarazzo Doppelgänger Buzz: a Full Timeline
By Sophia Al-Mansoor
Behind the uncanny visual parallels lies a documented medical explanation: Cleidocranial dysplasia (CCD). This rare genetic condition primarily affects the development of bones and teeth, occurring in approximately 1 out of every 1,000,000 individuals worldwide. It is caused by mutations in the RUNX2 gene, a master coordinator responsible for directing osteoblast differentiation during skeletal formation.
Common clinical features of CCD include underdeveloped or absent clavicles (allowing individuals to bring their shoulders together in front of their chest), delayed closure of skull sutures (fontanelles), prominent forehead bossing, hypertelorism (wide-set eyes), a depressed nasal bridge, and severe dental anomalies such as unerupted primary teeth and multiple supernumerary (extra) permanent teeth.
Because both Matarazzo and Shapiro have varying presentations of CCD, their facial anatomy shares distinct skeletal hallmarks. When Matarazzo auditioned for Stranger Things, the Duffer Brothers adjusted Dustin Henderson’s character arc specifically to reflect his condition, turning Matarazzo’s real-world speech patterns and missing front teeth into an integral, beloved character trait. Matarazzo took that visibility and partnered with the non-profit organization CCD Smiles, raising hundreds of thousands of dollars to fund costly corrective dental surgeries for lower-income families who cannot afford the specialized orthodontic procedures required to treat the condition.
