Additional information about the event may be found on the conference website: https://2017.eshg.org/ Sponsorship: Publication of this supplement is sponsored by the European Society of Human Genetics. All authors were asked to address any potential bias in their presentation and to declare any competing financial interests. These disclosures are listed at the end of each presentation. Contributions of up to EUR 10 000 (ten thousand euros, or equivalent value in kind) per year per company are considered "modest". Contributions above EUR 10 000 per year are considered "significant".

Virtually their only Maastricht, Netherlands function was to nominate somebody each year to organise a symposium on some aspect of human genetics.
