We apologise (16 September 2017) that access to the variant data in the three UCL-based enhanced databases (F7, F8 and F9) has been unavailable due to additional IT security measures being implemented. This important work to secure the DBs is now close to completion. Basic F8 variant/case data is mirrored to LOVD so may still be freely accessed there (see below).
You may select either the "enhanced" DB website which contains additional research tools and interpretations, or the LOVD common-format DB website developed in Leiden, if you prefer. The underlying basic genetic and phenotypic data in each DB are identical.
