Proqr Therapeutics N.v.
A biotechnology company in Leiden, the Netherlands, that develops RNA-based medicines for genetic diseases. It was founded in 2012 by Daniel de Boer, an IT entrepreneur who left his career after his newborn son was diagnosed with cystic fibrosis and set out to build a company to treat it. The "QR" in its name comes from its early drug candidates, which all carried the QR prefix.
