DBGen is a company founded by a team of specialized researchers in genetics at the University of Barcelona, who have been conducting basic research on genetic diseases of the retina for over 30 years.

Our team, which also includes experts in communications and management, as well as qualified technicians, is devoted to basic research and has contributed, through numerous publications, to identifying new pathogenic genes and mutations, and to building DNA diagnostic chips. The increased social demand for accurate genetic diagnoses from patients, associations and ophthalmologists is what drove us to create this genetic diagnostic service as a spin-off of the University of Barcelona.
