Building Your Care Team and Managing Symptoms

Managing a 15q13.3 microdeletion diagnosis is not about following a single, fixed path. Because this condition is defined by variable expressivity (the fact that symptoms vary wildly from person to person), your child’s care plan must be as unique as they are ^[1][2].

Building Your Multidisciplinary Team

The goal is to create a “medical home”—a group of specialists who communicate with each other to support your child’s whole health.

• Pediatric Neurologist: To monitor for brain-related symptoms, specifically epilepsy and hypotonia ^[3][4].
• Developmental Pediatrician: To oversee the big picture of your child’s growth, milestones, and educational needs ^[1].
• Medical Geneticist & Genetic Counselor: A geneticist explains the specifics of your child’s deletion, while a genetic counselor specializes in explaining inheritance, testing options, and family planning for siblings ^[5][6].
• Pediatric Psychiatrist: Especially as your child enters adolescence, to monitor for neuropsychiatric risks like anxiety, ADHD, or psychosis ^[7][1].
• Therapy Team: This includes Speech-Language Pathologists (SLP), Occupational Therapists (OT), and Physical Therapists (PT) to address communication, motor skills, and daily living tasks ^[1].
• Dietitian: To help establish healthy eating habits and manage weight if an increased risk for obesity presents itself ^[8].

Critical Baseline Evaluations

When a child is first diagnosed, doctors recommend several “baseline” tests to see where your child is starting and to catch issues that might not be visible on the surface.

1. Baseline EEG (Electroencephalogram): This is strongly recommended. Many children with this deletion have absence seizures (“staring spells”) that are very brief and easy to miss ^[3]. An EEG can catch this “silent” activity so it can be treated before it affects learning ^[9].
2. Developmental & ASD Assessment: A formal evaluation for developmental delays and Autism Spectrum Disorder (ASD) helps secure the right services in school and therapy ^[1][10].
3. Cardiac Screening: Although less common, some research suggests a potential link between this deletion and heart malformations ^[5][11]. A baseline evaluation by a cardiologist or an echocardiogram may be recommended.
4. Neuropsychological Baseline: Establishing a record of your child’s cognitive and behavioral strengths early on allows doctors to monitor for any changes as they grow ^[1].

Vetting Your Specialists

Not every doctor has experience with rare genetic deletions. Use this checklist when choosing members of your child’s team:

• [ ] Does the specialist have experience with neurodevelopmental disorders or rare genetic syndromes?
• [ ] Are they willing to collaborate with the other members of your child’s care team?
• [ ] Do they listen to your concerns and explain things in a way you can understand?
• [ ] Is the office prepared to handle the administrative needs of a complex care plan (e.g., insurance authorizations for therapy)?

A Focus on Anticipatory Guidance

The most important part of management is anticipatory guidance—staying one step ahead ^[1]. This means monitoring your child’s development and mental health even when they seem to be doing well. By having a team in place and baseline data recorded, you can act quickly if new challenges arise, ensuring your child has the best possible support at every stage of their life ^[5][10].
