Solidarity plays a relevant role in rare diseases (RDs) research to create and enable research in the field. In Europe RDs are estimated to affect between 27 and 36 million people even though single RDs can count very few patients, making the contribution of everyone essential to reach solid results. Often RD research is initiated by patient groups devoting substantial time and resources to the scientific enterprise. In RD research solidarity is often evocated and expressed, in different ways and on different levels, so that it is possible to talk about "solidarities" played by different stakeholders and sometimes conflicting with each other...
