20-22 June 2022
UMC Groningen, Netherlands

In 2020 a European consortium on Phelan-McDermid syndrome (PMS) started to write a best practice clinical guideline supported by the European Reference Network on neurodevelopmental disorders ERN-ITHACA. The consortium consists of over 70 members, representing 15 European countries and including 11 patient representatives. The group had their first online meeting in October 2020 and currently the guideline is nearing its completion. While working on the guideline, knowledge gaps were identified as well as the need for a European database enabling the collection of more data on the natural history of PMS, especially on the often observed mental health problems.

The consortium now is going to meet face-to-face in order to discuss the guideline recommendations and to strengthen the collaboration in order to tackle the knowledge gaps that we identified, as well as to discuss how best to proceed with the database. Most importantly, we are looking forward to discussions with our patient representatives who are invited to present their views early in the meeting programme.

The meeting will be hosted by the centre of expertise for PMS of the UMC Groningen, Netherlands, member of ERN-ITHACA and this Networking event has received funding from the European Union’s Horizon 2020 research and innovation programme under the EJP RD COFUND-EJP N° 825575.

The outcomes of the meeting will be:
– a strong collaboration between different European research groups and centres of expertise for Phelan-McDermid syndrome
– insight in the needs of the patient representatives and strengthen their participation in research- a priority list of knowledge gaps that need to be studied
– consensus on the variables to be collected in the European PMS database
