A Roadmap for Care: Medical Monitoring and Screenings

Because 1p36 deletion syndrome can affect many different parts of the body, a proactive “whole-child” approach to medical care is essential. While the diagnosis is rare, the medical community has identified key areas that require close attention. Screening for these conditions early is not just about gathering data—it is about identifying potential issues before they become serious ^[1][2].

The Heart: A Top Priority

Cardiac health is one of the most critical areas for monitoring. Many children with 1p36 deletion have structural heart differences or issues with how the heart muscle functions ^[3][4].

• Cardiomyopathy: A significant number of children may develop dilated cardiomyopathy (DCM), where the heart becomes enlarged and weakened, or left ventricular non-compaction (LVNC), where the heart muscle has a “spongy” appearance ^[5][4].
• Emergency Warning Signs: At home, you must watch for signs of heart failure. If your child exhibits rapid breathing, excessive sweating while feeding, or poor, pale skin color, you should seek emergency medical attention immediately ^[5].
• Surveillance: Baseline and periodic echocardiograms (heart ultrasounds) are standard practice ^[6][3]. Rest assured, an echocardiogram is a painless, non-invasive test involving only stickers and ultrasound gel on your child’s chest.

Neurological and Sensory Monitoring

The brain and nervous system require ongoing vigilance to manage development and safety.

• Seizure Screening: Given the high risk for epilepsy, doctors recommend a baseline EEG (electroencephalogram) to monitor brain activity, even if you haven’t seen a seizure yet ^[7][8]. Like an echocardiogram, an EEG is painless and involves placing small sensor stickers on the scalp.
• Vision and Hearing: Oculomotor anomalies, such as Duane retraction syndrome (which affects eye movement), and hearing loss are common ^[9]. Regular screenings with an audiologist and an ophthalmologist are recommended ^[1][2].

Other Systemic Considerations

Monitoring extends to the digestive, urinary, and skeletal systems.

• Gastrointestinal (GI): Doctors will watch for feeding difficulties and rare complications like biliary atresia ^[10]. Symptoms like jaundice (yellowing of the skin) or pale stools should be reported immediately ^[10].
• Renal and Orthopedic: Children should be screened for congenital differences in the kidneys and urinary tract, as well as for scoliosis (curvature of the spine) as they grow ^[1][11].
• Endocrine: Growth tracking and monitoring for issues like hypoglycemia (low blood sugar) are part of the long-term plan ^[4][12].

Baseline Surveillance Checklist

The following evaluations are typically recommended immediately following a diagnosis to establish a “baseline” of your child’s health.

Urgent Screenings:

• [ ] Cardiology: Full evaluation including an Echocardiogram and ECG to rule out life-threatening heart conditions ^[3][4].
• [ ] Neurology: Clinical exam and potentially a baseline EEG and brain MRI to look for seizures and brain structure differences ^[7][13].
• [ ] Renal/Abdominal Ultrasound: To screen for structural differences in the kidneys or urinary tract ^[1].

Routine Screenings:

• [ ] Ophthalmology: Comprehensive eye exam focusing on vision and eye movement ^[9].
• [ ] Audiology: Formal hearing test ^[1].
• [ ] Gastroenterology/Nutrition: Assessment of feeding safety and growth ^[10].
• [ ] Clinical Genetics: Review of the genetic report and discussion of family testing ^[14].
• [ ] Orthopedics: Baseline spine and hip evaluation ^[11].
