The Translational Genomics team focuses on the evaluation and optimization of novel genomic technologies for diagnostic implementation for the study of human genetic disease. Research has led to improved patient care by the implementation of array CGH for patients with intellectual disability (ID) into routine diagnostics as well as by the identification of novel syndromes and disease-causing genes.
In 2008, an obtained VENI grant was used to apply next generation sequencing to identify novel disease genes. The team was the first to use family-based whole exome sequencing for the identification of de novo mutations creating a paradigm shift in the field of medical genetics. Also, the achieved results provided a founding base to assess the diagnostic yield of exome sequencing in a routine diagnostic setting. The next frontiers in routine clinical diagnosis will, amongst others, include the implementation of whole genome sequencing as well as improving the clinical interpretation of (non-coding) genetic variation.

1. NWO VENI This research project focuses on how the combinations of genetic mutations can result in intellectual disability.
2. ZONMW TOP aims to extend a database with 10,000 clinically well characterized ID patients, to develop a universally applicable method that judges the likelihood of any conserved candidate gene to be an ID gene, generate disease-relevant functional data on at least a 100 candidate genes and validate 30-40 novel ID genes with specific ID phenotypes.
