Current Research Projects

The aim of my project is to identify the causative gene-defects in patients with autosomal recessive cone-rod dystrophy and Retinitis Pigmentosa. In the outbred Dutch population we previously found homozygous mutations in ~35% of patients with retinal dystrophy. We therefore hypothesize that the parents of these patients share a common ancestor that carries the disease-causing mutation, and that new disease genes can be identified by homozygosity mapping.

Methodology

In patients with an unknown cause for CRD we searched for sizeable homozygous regions using whole genome SNP arrays. In these regions we analyzed candidate genes for causative mutations.
