Coordinating Care: Symptom-Directed Treatments and Your Child's Team

While there is currently no cure for BCAP31-related syndrome (DDCH), a well-coordinated team of specialists can significantly improve your child’s comfort, communication, and quality of life. Because this condition is so rare, there is no single “standard” treatment manual; instead, care is symptom-directed, meaning it is tailored to your child’s specific needs as they change over time ^[1][2].

Building Your Multidisciplinary Care Team

Managing DDCH requires a “village” of medical professionals. A typical care team includes:

• Pediatric Neurologist: Often the lead specialist, they manage the movement disorder (dystonia), monitor for seizures, and track brain development ^[1][3].
• Audiologist & ENT: These specialists monitor hearing levels and evaluate whether technologies like hearing aids or cochlear implants are appropriate ^[1][4].
• Geneticist: They provide the formal diagnosis and help the family understand the inheritance pattern and risks for future children ^[2][4].
• Gastroenterologist (GI) & Pulmonologist: Because many children have feeding difficulties, liver issues, or respiratory vulnerability, these doctors monitor organ health and ensure proper nutrition ^[2][5].
• Therapy Team: Physical (PT), Occupational (OT), and Speech-Language (SLP) therapists are essential for supporting mobility and communication, starting from diagnosis ^[5].

Possible Symptom-Directed Treatments for Dystonia

Dystonia—involuntary muscle twisting and stiffness—can be one of the most challenging symptoms to manage. The goal of treatment is not to eliminate all movements, but to maximize comfort and function.

• Medications: Doctors may trial various oral medications extrapolated from other pediatric movement disorders, such as baclofen, benzodiazepines, or anticholinergics. It is important to know that these can cause significant side effects, including sedation, worsened hypotonia, respiratory depression, and swallowing difficulty. Medication decisions require a pediatric movement-disorder clinician ^[6].
• Focal Treatments: For stiffness in specific muscle groups, injections of botulinum toxin (Botox) are sometimes used to temporarily relax those muscles, bearing in mind risks of focal weakness or dysphagia ^[7].
• Physical Therapy: Regular PT focuses on preventing contractures (permanent shortening of muscles or tendons) and helping your child find comfortable positions for sitting and sleeping ^[2].

Hearing Rehabilitation and Communication

Since sensorineural hearing loss is a core feature of DDCH, early intervention is vital.

• Hearing Technologies: Some children benefit from high-powered hearing aids. In selected cases of profound hearing loss, cochlear implants have been used ^[1]. Candidacy for implants must be carefully evaluated by your team, as syndrome-specific outcome data is limited ^[8][9].
• Alternative Communication (AAC): Many families find success using Total Communication, which combines any residual hearing with sign language, gestures, and Augmentative and Alternative Communication (AAC) devices (like picture boards or tablets) to help their child express their needs.

Liver and Growth Monitoring

Because liver enzyme elevations (AST and ALT) are reported in some individuals, your child will likely need regular blood work to ensure their liver remains stable ^[2]. If your child has a “contiguous gene deletion” (CADDS), this monitoring becomes even more critical, as the risk for severe liver issues is higher ^[10].

Additionally, because many children face feeding challenges or “failure to thrive,” a nutritionist or feeding specialist can help adjust their diet or recommend specialized feeding equipment if necessary ^[5]. Focusing on these “baseline” health factors gives your child the best foundation for their development.
