Surveillance Recommendations

Management & Surveillance Recommendations

The TBRS Community would like to share a set of recommendations for initial clinical management and ongoing surveillance in TBRS. These recommendations were published in the GeneReview for Tatton Brown Rahman Syndrome (click here to view the full document).

These recommendations may be shared with clinicians and healthcare professionals to guide the clinical management of TBRS.

See recommendations below:

Initial Management Recommendations (immediately following TBRS diagnosis)

System Evaluation More information
Constitutional Measurement of weight, length/height, & head circumference Assess for macrosomia.
Development Developmental assessment Assess motor, adaptive, cognitive, & speech/language evaluation. Evaluate for early intervention / special education.
Psychiatric / Behavioral Neuropsychiatric evaluation (For individuals over 12 months) screening for behavior concerns including sleep disturbances, ADHD, anxiety, & traits suggestive of ASD.
Neurologic Neurologic evaluation Consider brain MRI (if clinical symptoms) & consider EEG (if seizures are a concern).
Musculoskeletal Orthopedics / physical medicine & rehab / PT & OT evaluation Assessment of gross & fine motor skills, joint hypermobility, kyphoscoliosis, mobility, ADL, need for adaptive devices, & need for physical / occupational therapy.
Cardiovascular Baseline echocardiogram Assess for structural heart defects & aortic dilatation.
Respiratory Polysomnography Assess for sleep apnea (if suggested by clinical symptoms).
Genitourinary Exam for cryptorchidism in males Consider assessment for vesicoureteral reflux in those with a history of recurrent urinary tract infections.
Hematologic / Lymphatic Consider complete blood count (CBC) with differential Inform patients/families of potential risk of hematologic malignancy, with an emphasis on symptom awareness. A low threshold should be adopted for investigation for malignancy (in case of symptoms).
Genetic counseling By genetics professionals Inform affected persons & their families of the nature, inheritance, & implications of TBRS to facilitate medical & personal decision making.
Family support & resources Assess the need for community support or online resources, social work involvement for parental support, & home nursing referral.

Ongoing Surveillance Recommendations

System Evaluation Frequency
Development Monitor developmental progress & educational needs. Every visit
Psychiatric / Behavioral Behavior assessment for anxiety, attention, & aggressive or self-injurious behavior. Every visit
Neurologic Monitor those with seizures. Assess for new manifestations such as seizures & changes in tone. Every visit
Musculoskeletal Physical medicine, occupational / physical therapy assessment of mobility, kyphoscoliosis, & pain. Every visit
Respiratory Assess for signs & symptoms of sleep apnea & infections. Every visit
Hematologic / Lymphatic Assess for signs & symptoms of blood malignancy. Every visit
Family / Community Assess family need for social work support & care coordination. Every visit
Cardiovascular Echocardiogram to assess aortic root indices. Ongoing surveillance will be determined by size of aortic root, advice of cardiologist, health care framework, & data from longitudinal studies.
