Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Seizures
Epileptic episodes that may vary in type and frequency, requiring neurological evaluation and management.
Seek immediate medical attention if seizures occur or if seizure patterns change.
Congenital heart defects
Structural heart abnormalities such as atrial septal defects, ventricular septal defects, or other cardiac malformations.
Cardiac evaluation with echocardiogram is essential; seek urgent care if symptoms of heart failure develop.
Developmental delay
(constitutional)Delayed attainment of developmental milestones such as sitting, walking, and speaking compared to typical peers.
Frequency: 90-100% of patients
Growth retardation
(constitutional)Slowed growth in both height and weight, often noted in infancy and continuing through childhood.
Frequency: 80-90% of patients
Facial dysmorphism
(neurologic)Characteristic facial features including prominent forehead, deep-set eyes, short nose, and abnormal ear placement.
Frequency: 85-95% of patients
Hypotonia
(neurologic)Reduced muscle tone present from infancy, affecting motor development and coordination.
Frequency: 50-70% of patients
Behavioral problems
(behavioral)Issues including attention deficits, hyperactivity, autism spectrum traits, or aggressive behaviors.
Frequency: 50-70% of patients
Genitourinary anomalies
(genitourinary)Structural abnormalities of the kidneys, bladder, or genitalia, including cryptorchidism in males.
Frequency: 15-25% of patients
Microcephaly
(neurologic)Abnormally small head circumference due to reduced brain growth, often associated with developmental impacts.
Frequency: 10-20% of patients
Feeding difficulties
(gastrointestinal)Problems with feeding and swallowing that may require nutritional support in infancy.
Frequency: 5-15% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Developmental Milestone Surveillance
Regular developmental assessments and screening for associated features including growth parameters, cardiac evaluation, and neurological examination with early intervention referral as needed.
Early Intervention Physical Therapy
Structured physical therapy program targeting motor delays, muscle tone abnormalities, and promoting age-appropriate gross motor skill acquisition through play-based activities.
Additional treatment options
Cognitive and Behavioral Support
Neuropsychological evaluation and targeted interventions for learning difficulties, attention deficits, and behavioral challenges associated with the genetic condition.
psychologicalSpecialty Imaging Studies
Periodic brain MRI and other imaging studies as indicated by clinical findings to assess for structural brain abnormalities or changes over time.
procedureFamily Education and Genetic Counseling
Comprehensive genetic counseling for affected individuals and families to understand the condition, inheritance patterns, recurrence risks, and available support resources.
