-[``lovdtools``](https://github.com/hyletic/lovdtools.git) is a Python package that provides configurable utilities for acquiring variant records from the Global Variome shared Leiden Open Variation Database (LOVD) instance. It abstracts away much of the complexity surrounding large-scale data requisitions by wrapping the LOVD data retrieval API in a fluent Python interface suitable both for scripting and interactive use cases. Originally written to support his ongoing research on genotypic variance in the manifestation of the Ehlers–Danlos Syndromes, this tool is provided by [``@hyletic``](https://github.com/hyletic) to the public, free of charge, in hopes that it might one day serve to make these data more accessible to clinicians, researchers, and patients alike.
