---|---|
Autosomal dominant pattern is the inheritance manner of this condition | |
Specialty | Medical genetics |
Causes | Mutations in the CREBBP gene |
Signs and symptoms
editThe feature of this condition include
- Microcephaly
- Ventriculomegaly
- Absent corpus callosum
- Autistic behavior
- Feeding problems
- Epilepsy
- Variable intellectual disability
- Staphyloma
- Cochlear malformations
- Mild hearing impairment
- Exomphalos
- Short stature
- Recurrent upper airway infections
Genetics
editThis condition has been associated with mutations in the CREB binding protein gene (CREBBP). This gene is located on the short arm of chromosome 16 (16p13.3).
Pathopysiology
editThe pathogenesis of this condition is not understood.[citation needed]
Diagnosis
editThis syndrome may be suspected on clinical grounds. The diagnosis is established by sequencing the CREBBP gene.[citation needed]
Differential diagnosis
editTreatment
editThere is no specific treatment for this condition. Management is supportive.[citation needed]
Epidemiology
editThis condition is considered to be rare with less than 20 cases reported in the literature.[citation needed]
History
