Introduction to Gaten Matarazzo and CCD

Gaten Matarazzo is best known for portraying Dustin Henderson on the global streaming phenomenon Stranger Things. He was born with cleidocranial dysplasia (CCD), a rare genetic condition affecting bone development, particularly the clavicles and skull. CCD can influence dental eruption, sinus formation, and bone density. Matarazzo has used his high-profile platform to explain the condition accurately, distinguish fact from fiction, and advocate for greater public understanding. This profile frames his condition, career trajectory, and public footprint in a durable, factual manner.

What Is Cleidocranial Dysplasia?

Medical Definition and Genetics

Cleidocranial dysplasia is a hereditary disorder caused primarily by mutations in the RUNX2 gene. It is inherited in an autosomal dominant pattern, meaning a single copy of the altered gene can cause the condition. CCD affects skeletal development, commonly resulting in underdeveloped or absent clavicles, a widened skull, delayed closure of fontanelles, and dental abnormalities such as delayed eruption or supernumerary teeth. While many individuals with CCD lead full lives, the condition requires ongoing medical and dental oversight.

Common Signs and Management

• Hypoplastic or absent clavicles, allowing greater shoulder mobility
• Skull and facial bone differences, sometimes affecting sinus size
• Delayed tooth eruption and orthodontic challenges
• Variable hearing and sinus health considerations

Treatment is individualized and may involve orthodontics, surgical dental care, physical therapy, and periodic audiology evaluation. Matarazzo has described how CCD shaped his childhood experiences without defining his personal or professional limits.
