Anna de Burca (Oxford University Hospitals NHS Foundation Trust)

Green List (high evidence)

Non-specific intracranial features but can include abnormalities of corpus callosum & posterior fossa, as well as mild skeletal features e.g. hemivertebrae, micrognathia. Associated with moderate to severe developmental delay with limited/absent speech and limited mobility, so important diagnosis to make.
