bookmark LOVD / Leiden Open Variation Database Provide a flexible, freely available tool for Gene-centered collection and display of DNA variations. LOVD 3.0 extends this idea to also provide patient-centered data storage and storage of NGS data, even of variants outside of genes. LOVD allows users to link large numbers of DNA variants in one or more genes to an individual (multi-gene disorders or large scale next-generation sequencing). You can even use LOVD on your personal computer to browse through the variants in your own exome/genome. To maintain a high quality of the data stored, LOVD connects with various resources, like HGNC, NCBI, EBI and Mutalyzer.
