In the EU alone, according to the Orphanet DB (https://pubmed.ncbi.nlm.nih.gov/31527858/), 30 million persons, 3,5-6% of the general population, are affected by one of the 6,172 different rare diseases (RDs) of which 72% are genetic and 70% affect children. The path to diagnosis for people suffering from a RD is burdensome, often severely delayed by a diagnostic odyssey. Lack of timely diagnosis affects disease management, family planning, identification of potential beneficial treatments and / or clinical trials. This unacceptable situation does not meet the concept of equity for EU citizens, and requires rapid, structured, and cost-effective corrective actions. The Screen4Care (S4C) consortium will leverage the genomic and digital advent to develop and pilot genetic NBS and AI-guided symptom recognition algorithms, while accounting for all relevant legal, regulatory and ethical considerations. S4C aims to harmonize the results of existing efforts in a horizon scan, by looking at the totality of the available data resources, diagnostic algorithms, and other initiatives with similar ultimate goals. The genetic NBS will interrogate 1) currently treatable RDs (TREAT-map gene panel), 2) actionable RDs (ACT-map gene panel) in 18.000 new-borns in 3 EU countries (D, It, and Cz). Further, S4C will offer whole genome sequencing (WGS) to early symptomatic babies, tested negatively during panel-based NBS to identify known NBS-escaped RDs and novel genes/phenotypes. S4C will also provide two digital diagnosis support systems for RD on the basis of features and symptom complexes: 1) federated ML- and literature-evidence-based algorithm for continuous and automated screening of EHR and 2) meta symptom checker with virtual clinics for patients and HCP offering the possibility of increased accuracy of diagnosis and ongoing supports. Our ambitious goal is to evaluate the validity of our multi-pronged approach to shorten the time to diagnosis for all patients affect by RDs, improve value-based healthcare resource utilization, and hopefully reduce the suffering of millions of European citizens.

Cystic fibrosis (CF) is a progressive life-shortening disease caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene leading to a dysfunctional CFTR protein. The disease affects over 70,000 patients worldwide and while many mutations are known, the F508del mutation affects 90% of all patients. The absence of CFTR in the plasma membrane leads to a dramatic decrease in chloride efflux, resulting in viscous mucus that causes severe symptoms in vital organs like the lungs and intestines. For CF patients that suffer from the life threatening F508del mutation only palliative treatment exist. PRO-CF-MED addresses the specific challenge of this call by introducing the first disease modifying medication for the treatment of the CF patients with F508del mutation. The PRO-CF-MED project has been designed to assess the potential clinical efficacy of QR-010, an innovative disease modifying oligonucleotide-based treatment for F508del patients. Partners within PRO-CF-MED have generated very promising preclinical evidence for QR-010 which allows for further clinical assessment of QR-010 in clinical trials. PRO-CF-MED will enable the fast translation of QR-010 towards clinical practice and market authorisation. PRO-CF-MED has the potential to transform this life-threatening condition into a manageable one.

StarT will create an interdisciplinary and intersectorial European training network focusing on different aspects of autosomal recessive Stargardt disease (STGD1), a frequent inherited blinding disorder that affects an estimated 925,000 persons worldwide. StarT research aims to uncover the regulation of its disease gene ABCA4 and its missing heritability, in order to develop novel treatments. StarT training will give young researchers unparalleled training opportunities in outstanding vision research groups with unique expertise in omics technologies, bio-informatics, stem cell biology, animal models of disease, and therapeutics, providing each ESR with the necessary competences in state-of-the-art academic and industrial research. STGD1 is due to ABCA4 mutations, however up to 35% of STGD1 cases carries one or no ABCA4 coding mutation. New unconventional classes of ABCA4 mutations were recently discovered by us, the significance of which largely remains elusive. In order to understand the mechanisms triggered by these missing ABCA4 mutations and to design new therapies for STGD1 cases, challenging research questions will be addressed by the integration of unique skills from this network. Early-Stage Researchers will perform cutting edge research using innovative and interdisciplinary approaches: (functional) genomics and transcriptomics, bio-informatics, CRISPR/Cas9 genome editing, generation of stem cell and animal disease models and design of new treatments. The training objectives will be met through academic and industrial training-by-research via individual research projects, secondments, and network-wide training sessions.
