What symptoms should we monitor for Cri du Chat syndrome?
Families should watch for changes in feeding and growth, since many children have challenges with reflux, chewing, or swallowing. Monitor your child's motor development, as low muscle tone can affect how they sit, crawl, stand, or walk. Most children with Cri du Chat have difficulty with language, though they typically understand more than they can express; discuss speech therapy or AAC options early if speech is delayed.
Dental health also needs attention: common concerns include a high palate, jaw differences, delayed tooth eruption, weak enamel, teeth grinding, and erosion from reflux, so early care with a dentist experienced in special needs is important.
Children with Cri du Chat may also experience hearing or vision differences. Some have heart or kidney differences identified early in life. Sleep challenges, constipation, and drooling are relatively common as well. Seizures occur in some children, though not all.
While not all children experience seizures, ask your provider what to watch for. Report any new or worsening symptoms to your care team so they can guide next steps.
What is the expected progression of Cri du Chat syndrome?
Cri du Chat syndrome looks different in every child. Children grow and develop in their own way and at their own pace. Many continue to gain new skills over time, even if learning, communication, or movement takes longer than expected.
The high-pitched cry that is often noticed in infancy usually becomes less noticeable as children get older. For many families, it fades within the first few years of life.
Some physical features also change naturally over time. For example, the round facial appearance often seen in babies may become longer and more defined with age. Muscle tone can change as children grow, and posture or spine shape may shift during childhood or adolescence.
Most importantly, children with Cri du Chat continue to learn, connect, and develop throughout childhood and beyond. Families often describe seeing steady growth in communication, personality, relationships, and independence over time.
What treatments are available for Cri du Chat syndrome?
There is currently no cure for Cri du Chat syndrome, but supportive care and therapies can make a meaningful difference in your child's development and quality of life. Your care team will work with you to build a plan tailored to their needs. We'll share more details about specific therapies and interventions in Section 3.
Who else should be on our care team?
Children with Cri du Chat syndrome often benefit from a team of specialists.
Depending on your child's needs, this may include a cardiologist (heart defects occur in 15–20% of children), an ENT specialist for hearing, swallowing, and ear infections, a gastroenterologist for reflux or constipation, an orthopedist for flat feet or scoliosis, an ophthalmologist for vision concerns, an audiologist for hearing assessments, and a dentist for jaw and teeth alignment.
A geneticist can help coordinate care across specialties.
If your child ever needs surgery, it may be helpful to let the anesthesiologist know about Cri du Chat syndrome, as airway differences could require special planning.
Finding clinical trial opportunities & supporting research into Cri du Chat syndrome
When you participate in research, you help your child and other families in the future. Medical research studies can be very different from each other. Some test new treatments, while others are "natural history studies" that just collect information about a disease’s impact over time.
Clinical trials are research studies that help doctors find new treatments. Some trials test new medicines or therapies that aren't available yet. Even if you may choose not to participate, it can be good to know what options exist for your child's condition. Your child's doctor or disease organization can help you find trials that might be a good fit. The U.S. government also maintains a registry at clinicaltrials.gov
Natural history studies are designed to help researchers learn more about the condition. This information is important for creating future treatments. Traditional natural history studies can involve additional medical appointments over the course of several years.
Patient registries collect health information from people with specific diseases to help research move faster and connect families with clinical trials. Registries also show researchers and drug companies that families are engaged and want to help develop new treatments, which can bring more funding and research attention to a disease. Some diseases have more than one registry you can join. Patient Advocacy Groups typically establish and maintain patient registries for specific rare diseases. (See Section 5 below to learn more).
Organizing and maintaining your child’s medical records for Cri du Chat syndrome
Rare disease patients see many different doctors, often across different medical and technological systems that may not talk to each other. Unfortunately, that means the burden often falls on caregivers to track care holistically, identify “gaps,” and make sure nothing gets missed. Keeping your records as organized and centralized as you can from early on is likely to improve your ability to manage your child’s care down the road.
You can start by creating a one-page sheet with your child's diagnosis, current medications, allergies, and emergency contacts. Bring this sheet to every appointment. It can really help in emergencies or when you see a new doctor.
Many caregivers establish one (or several) records binder(s) in which they keep track of appointments, medication updates, symptoms, and other ongoing medically relevant information.
We also encourage caregivers to consider Citizen Health’s free tools for centralizing, managing, accessing, and extracting key information from health records. Our system will collect all your health records, across doctors and health systems, making them available on our secure online platform that can provide answers in real time based on questions you ask (like “What medications has my child been prescribed in the past year?” or “When did we last see an orthopedist?”)
As a company built by rare disease caregivers, we aim to overcome the need for physical records binders. But ultimately the important question is what works for you and your family.
