Rare disease research area has a significant demand for the biological samples and associated phenotype and genomic information. Scarcity of the data and samples available for research purposes is well recognised obstacle on the way of translational research. RD-Connect offers a solution to this issue in a form of RD-Connect Registry and Biobank Finder tool. RD-Connect is a 6 years global infrastructure project initiated in November 2012 that links genomic data with patient registries, biobanks, and clinical bioinformatics tools to create a central research resource for RDs (1). The finder comprises aggregated up to date information on 62 000 biological samples available across 21 biobanks from more than 15 countries worldwide. The tool is easy to navigate and user friendly. The finder is also a portal to other RD-Connect tools, providing a link to the RD-Connect Sample Catalogue, a large inventory of RD biological samples available in participating biobanks for RD research.
