Gene Regulation: Elzo de Wit

About Elzo de Wit

Genome function and dynamics

From genotype to phenotype
Technological advances in DNA sequencing have made the €1000 genome a reality. This will usher in an era of personal genomics. One of the key challenges in this burgeoning field will be to understand how genetic variation leads to differences between individuals. Years of human genetics research has identified thousands of genetic regions associated with human traits and disease. Many of these this genetic regions are in non-coding regions of the genome. Predicting the effect of non-coding variation is, compared to coding variants, far from trivial. We have developed tools that allow the linkage of genetic variants on the same chromosome, to create so-called haplotypes. Haplotypes will help us to better predict the effect of a genetic variant on gene expression.

3D organization of the genome
Storage of our DNA inside the nucleus is a formidable task. When stretched out our genome measures 2 meters in length. But it has to fit into a nucleus that is one 100th of a millimeter in diameter. To achieve this the genome is very efficiently folded. It has become clear that the 3D organization of the genome plays an important role in the regulation of genes. We have been at the forefront of the development of tools that analyze how the genome is folded, such as 4C and Hi-C. We continue to develop these tools to better understand the interplay between genome folding and gene expression.

I started my PhD in 2015 in the lab of Elzo de Wit, where I will be working on a computational framework for linking haplotypes to differences in gene expression.
I finished my master in Cancer, Stem cells and Development at the Utrecht University with honors. My first internship was in the lab of Edwin Cuppen at the Hubrecht Institute, where I looked at often discarded pieces of information from DNA-sequencing. I did my  second internship in Cambridge in the lab of Dave Adams. Here I studied melanoma-predisposition mutation-clusters in the non-coding regions of the genome.

PhD student


I obtained my bachelor degree in Biology at the University of Amsterdam (UvA) and my master degree in Bioinformatics also at the UvA in combination with the VU university. For the first research project I joined the Biosytems Data Analysis Group. The project involved applying machine learning to predict age from DNA methylation. The resulting model was subsequently used to develop a wet lab protocol for forensic science. The second project was at DSM in the genetics department. I worked with Pacific Biosciences sequence data to characterize DNA methylation in one of their industrially deployed microorganisms.
