Eye Genetics Group
Inherited eye diseases are complex and numerous group of sight-threatening conditions. The focus of the research group is a detailed clinical phenotypic characterization of genetic eye diseases, gene discovery, functional testing of variants in laboratory assays, and ultimately development treatments. We utilize up-to-date genetics methods including exome, whole-genome, and long-read sequencing. We perform chemical and cellular assays as well as use CRISPR/CAS9-technology.
Uveal melanoma genetics and BAP1 cancer syndrome: Uveal melanoma is the most common primary intraocular cancer. It metastasizes in approximately one-half of patients. For reasons unknown, the incidence of uveal melanoma is highest in northern latitudes. In Finland, all uveal melanoma patients are treated in the Helsinki University Hospital. Therefore, we have a population-wide patient collection. We have reported that 2% of Finnish uveal melanoma patients harbor a mutation in the BAP1 gene, but this explains only 25% of familial cases. Currently, we are functionally characterizing the Finnish variants in the BAP1 gene. Furthermore, we are searching for new genes predisposing to uveal melanoma using next-generation sequencing techniques.
Inherited corneal diseases: Our latest discovery is the gene behind keratitis fugax hereditaria, peculiar periodic corneal autoinflammation. The variant in the inflammasome gene NLRP3 causes this syndrome, and currently, we are functionally testing the effects of this variant in peripheral white cells, and examine potential treatments. Furthermore, we are investigating several corneal dystrophies (TGFBI-dystrophies, posterior polymorphous corneal dystrophy, Fuchs corneal dystrophy) to elucidate their genetic background in Finland
Inherited retinal diseases: Approximately 60-70% of inherited retinal dystrophies, including retinitis pigmentosa and macular dystrophy, are genetically solved. We are collecting DNA samples and phenotypic information for the large-scale discovery of new variants and genes behind genetically unsolved diseases.
Early-onset glaucoma: We are investigating the genetic background of juvenile open-angle glaucoma. We will utilize exome sequencing to identify new glaucoma genes.
