Building Your Care Team

Because SLC35A2-CDG is an ultra-rare condition that affects multiple systems—especially the brain and metabolism—it cannot be managed by a single doctor. You will need to build a multidisciplinary team, a group of specialists who work together to coordinate your child’s care ^[1][2].

The Core Medical Team

Your “home base” will typically consist of several main specialists who share care for the most critical aspects of the disease:

1. Biochemical Geneticist (Metabolic Specialist): They are the experts in how your child’s body processes sugars. They will:
   • Interpret complex genetic reports, including low-level mosaicism ^[1].
   • Manage and calculate the precise dosing for D-galactose therapy ^[3].
   • Direct individualized monitoring for clinical development and safety outcomes while coordinating with the broader team ^[3].
2. Pediatric Epileptologist (Neurologist): While many neurologists treat seizures, an epileptologist specializes in difficult-to-treat cases like those seen in SLC35A2-CDG ^[4]. They will manage the EEG monitoring, treat infantile spasms, and evaluate if your child has a specific brain malformation called MOGHE that might require surgical consultation ^[5][6].
3. Genetic Counselor: A specialist to discuss family planning, interpretation of genetic testing (including Variant Allele Fractions), and coordinate parental or recurrence-risk testing ^[1].
4. Rehabilitation and Developmental Team: Because of the high risk of hypotonia (low muscle tone) and developmental delays, your child will likely need a team of therapists ^[2]:
   • Physical Therapists (PT): To work on motor skills, head control, and mobility.
   • Occupational Therapists (OT): To help with “activities of daily living” and fine motor skills like grasping.
   • Speech and Feeding Specialists: Crucial for managing swallowing difficulties and helping your child develop communication tools ^[3].

Essential Items for Your First Appointment

Rare disease specialists often have long waitlists, so you want to make the most of your first visit. Do not rely entirely on the hospital to send records electronically; bring a physical “care binder” or ensure secure electronic access for:

• The Full Genetic Report: Ensure it includes the Variant Allele Fraction (VAF). This helps the doctor interpret if the mutation is “mosaic” (only in some cells) or present in every cell ^[5].
• MRI Images: Request secure access or the institution’s preferred DICOM-sharing method. Doctors need to see the actual images of the brain’s white matter and the corpus callosum, not just the written summary from a radiologist ^[2].
• EEG Reports: Summaries of brain wave patterns, especially if they mention hypsarrhythmia ^[7].
• A Seizure Diary: A log of what the seizures look like, how long they last, and what time of day they occur. Videos of the movements on your phone can also be incredibly helpful for the doctor.

Vetting Your Doctors

Not every specialist will have heard of SLC35A2-CDG. It is okay to “interview” your doctors to ensure they are the right fit for your family. You might ask:

• “Are you familiar with the use of investigational therapies like D-galactose for CDGs, or are you willing to consult with a national CDG center to manage it?” ^[3]
• “How do you typically manage drug-resistant epilepsy in children with metabolic disorders?” ^[4]
• “Do you have experience with MOGHE or other focal brain malformations?” ^[5]

By gathering the right experts and coming prepared with your child’s data, you move from being a passenger in the medical process to being an active, informed advocate for your child.
