Deciphering Developmental Disorders - Overview
The Deciphering Developmental Disorders (DDD) Study has recruited nearly 14,000 children with severe undiagnosed developmental disorders, and their parents from around the UK and Ireland. The patients have been deeply phenotyped by their referring clinician via DECIPHER using the Human Phenotype Ontology.
Samples have been collected at the Wellcome Sanger Institute, where we are applying high resolution exon-arrayCGH and trio exome sequencing to investigate the genetic causes of abnormal development. Likely diagnostic results are being reported to clinical teams, for validation and communication with families, and will all be made publicly available via DECIPHER.
We hope that the findings from DDD will help design more efficient and cheaper diagnostic assays for relevant genetic testing to be offered to all such patients in the UK and so transform clinical practice for children with abnormal development.
