Gaten Matarazzo Disease: Symptoms, Causes, and Treatment Options

“Gaten Matarazzo disease” is a common public-facing way to refer to cleidocranial dysplasia, the rare genetic condition the actor has spoken about publicly. It mainly affects bone and tooth development, and while there is no cure, many symptoms can be managed with coordinated medical and dental care.

Overview: What is “Gaten Matarazzo disease”?

“Gaten Matarazzo disease” is not the formal medical name of a disease. In most cases, people using this term are asking about cleidocranial dysplasia, a rare genetic condition that affects the development of bones and teeth. The term became widely searched because actor Gaten Matarazzo has publicly shared that he lives with this condition.

Cleidocranial dysplasia can vary greatly from one person to another. Some people have mild signs that are noticed mainly during dental care, while others have more obvious skeletal differences from early childhood. The condition often involves the skull, collarbones, jaw, teeth, and overall growth pattern.

Although cleidocranial dysplasia is lifelong, it is usually manageable with planned follow-up and the right mix of specialists. Care often includes pediatricians, geneticists, dentists, orthodontists, oral and maxillofacial surgeons, orthopedists, and hearing specialists. The aim is to support function, comfort, and healthy development over time.

Signs and symptoms

The symptoms of cleidocranial dysplasia often center on the skeleton and teeth. One of the best-known features is underdeveloped or absent collarbones, which may allow the shoulders to move unusually close together in front of the body. Many children also have delayed closure of the soft spots of the skull, a broad forehead, and a head shape that may appear different from average.

Dental findings are especially common. Baby teeth may fall out late, adult teeth may come in late or not erupt on time, and extra teeth may develop. Crowding, bite problems, and jaw alignment changes can also occur. Because of these issues, dental and orthodontic care is often an important part of treatment planning.

Other possible features include short stature, differences in the shape of the pelvis, scoliosis, flat feet, recurrent ear infections, or hearing difficulties. Some people have sinus or upper airway issues. Intelligence is usually unaffected, but living with a visible genetic condition can sometimes affect confidence, daily comfort, or social well-being, especially during childhood and adolescence.

• Delayed loss of baby teeth
• Delayed or blocked eruption of permanent teeth
• Extra teeth
• Underdeveloped or absent collarbones
• Broad forehead or persistent open skull sutures
• Short stature or other skeletal differences
• Possible hearing or ear-related problems

Causes and risk factors

Cleidocranial dysplasia is usually caused by a change in the RUNX2 gene. This gene helps control bone and cartilage development, especially the formation of the skull, collarbones, and teeth. When the gene does not work as expected, normal bone and tooth development can be altered.

The condition is commonly inherited in an autosomal dominant pattern. This means a child may develop the condition if one parent carries the altered gene. However, some people have no family history, and the genetic change happens for the first time in that individual. In these cases, the diagnosis can come as a surprise to families.

There are no lifestyle choices, foods, or environmental exposures known to cause cleidocranial dysplasia. Risk is mainly genetic. If a person has the condition or a family history of it, genetic counseling can help explain inheritance patterns, the chance of passing it on, and what testing options may be available for family members.

How the condition affects daily life

One useful way to understand gaten matarazzo disease is to look beyond the diagnosis name and consider how it can affect daily life. For many children, the most persistent concerns involve dental development. Delayed tooth eruption, extra teeth, and jaw crowding may affect chewing, speech, oral hygiene, and appearance, often requiring long-term dental planning.

Musculoskeletal differences may also influence activity and posture. Some people have shoulder mobility that is greater than usual because of clavicle changes, while others may experience back or foot issues that need monitoring. Most individuals can take part in school, play, and everyday routines, but some benefit from tailored support or periodic assessment by orthopedic specialists.

Because the condition is visible in some cases, emotional support can be just as important as physical care. Children and teenagers may have questions about appearance, repeated appointments, or feeling different from peers. Families often find that clear explanations, supportive school communication, and steady follow-up make a meaningful difference.

Diagnosis

Diagnosis usually begins with a medical history and physical examination. A doctor may notice features such as unusual shoulder movement, delayed closure of skull bones, short stature, or a pattern of dental eruption that suggests a genetic skeletal condition. Family history can also provide important clues.

Imaging studies are often used to confirm the diagnosis and understand the extent of bone involvement. X-rays may show absent or partially formed collarbones, open skull sutures, extra teeth, or changes in the pelvis and spine. A full dental assessment is usually recommended because tooth development can be one of the most important parts of long-term care.

Genetic testing may be offered to look for a RUNX2 gene change. This can help confirm cleidocranial dysplasia and support family counseling. In some cases, doctors may also consider other genetic or skeletal conditions in the differential diagnosis, especially if the presentation is not typical. Care is often individualized, since the exact combination of symptoms varies from person to person.

Treatment options and long-term management

There is no single cure that reverses cleidocranial dysplasia, so treatment focuses on the person’s specific symptoms and stage of development. The most common need is coordinated dental care. This may include monitoring baby and adult teeth, planning orthodontic treatment, and creating a timeline for procedures that help impacted or delayed teeth erupt more normally.

When needed, doctors may recommend orthodontic treatment or oral and dental surgery to address extra teeth, crowding, or unerupted permanent teeth. Some patients also need orthopedic follow-up for posture, spinal alignment, foot structure, or other skeletal concerns. Hearing evaluations may be useful if recurrent ear problems or hearing changes are present.

Children often benefit from care in a multidisciplinary setting where specialists can coordinate timing and priorities. This is especially important because treatment plans may extend over several years as the skull, jaws, and teeth continue to develop. For patients who need advanced imaging or complex planning, dental treatment may be combined with surgical and orthodontic input to improve both function and appearance.

Near the end of the care journey, some families also seek consultation at centers with experience in rare skeletal and dental conditions. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat complex conditions for international patients, including coordinated evaluation when cleidocranial dysplasia is suspected.

Self-care, family support, and prevention

Because cleidocranial dysplasia is genetic, it cannot usually be prevented through lifestyle measures. However, early recognition can help prevent complications such as severe dental crowding, untreated impacted teeth, bite problems, or avoidable delays in supportive care. Regular follow-up is one of the most important steps families can take.

Good oral hygiene is especially important. Brushing, flossing, and routine dental visits can help protect teeth and gums while treatment is being planned. Families may also benefit from keeping records of imaging, dental timelines, and specialist recommendations so that long-term care remains organized.

Children should be encouraged to stay active unless a doctor advises restrictions for a specific orthopedic reason. Balanced nutrition, routine hearing checks if needed, and emotional support at home and school can all help. For families planning future pregnancies, genetic counseling can provide practical information about inheritance and testing options.

When to seek medical care

Medical or dental assessment is appropriate if a child has delayed tooth eruption, baby teeth that do not fall out on time, unusually mobile shoulders, a persistently open soft spot on the head, or a family history of cleidocranial dysplasia. These signs do not always mean the condition is present, but they do justify professional evaluation.

Prompt review is also important if there is pain, swelling in the mouth or jaw, suspected hearing loss, repeated ear infections, back deformity, or concerns about growth and posture. A specialist can help decide whether imaging, dental referral, hearing tests, or genetic evaluation are needed.

If symptoms are affecting eating, speech, breathing during sleep, school confidence, or social well-being, families should mention this during the consultation. Early, supportive care can improve comfort and planning. In general, a child’s pediatrician, family doctor, dentist, or orthodontist can help guide the first steps and refer to the right specialists.
