Since the publication of previous guidelines in 2006, the use of genetic techniques including array comparative genomic hybridisation (array CGH) and more recently exome/genome sequencing have led to significant advances in identifying the causes of Intellectual Disability (ID) / Developmental Delay (DD).
The ID group has now revised the 2006 guidelines to include a diagnostic flowchart for clinicians supported by updated evidence and new parents’ guides. These new documents, produced on behalf of the ID group by the PHG Foundation, can be downloaded from the links below.
