The bank of primary immunodeficiencies of Vall d'Hebron has collected 100 samples from patients with these rare diseases and their relatives, since its beginning in January 2015.This collection allows the disposal of the samples when required in order to carry out functional and/or genetic studies at national and international level. Dr. Pere Soler, head of the Immunocompromised Patient group at Vall d'Hebron Institute of Research (VHIR), says that "the biobank offers clear benefits to patients and research in this field, since with these samples, which are collected in a standardized model, we can investigate these diseases, optimize the diagnosis and offer genetic counseling to the closest relatives". At the moment, all the samples have been collected at Vall d'Hebron University Hospital and some of them have been sent to a research group located in Friburg, Germany.VHIR's project has received the support of the http://www.pidfoundationbcn.org/" BCN-PID Foundation, the http://www.acadip.org/ca.html" Catalan Association for Primary Immunodeficiencies (ACADIP) and the campaign http://www.totsambdidac.com/" 'Tots amb Didac'.
