PROJECT SUMMARY The main goal of the RUNX1 Research Program 8th Annual Scientific Conference and Patient Meeting is to create a dynamic convening in order to foster collaboration and provide opportunities for knowledge and data sharing among a diverse set of researchers, clinicians, and patients and their families for a rare disease called RUNX1 familial platelet disorder with predisposition to hematologic malignancies (RUNX1-FPD or FPDMM). Individuals with the disorder have a 35-50% lifetime risk of developing a hematologic malignancy. Of those who develop a malignancy, over 50% are diagnosed with AML. It is the only convening of its kind and continues to be an important part of discovery and future therapies for the disorder as well as an opportunity for early career investigators, posts and graduate students to present their research. Conference participation has grown each year. We had over 181 attendees for the virtual conference in 2021. In 2022, we had 130 individuals - 40 patients and 90 scientists, clinicians and genetic counselors - who attended in-person in Princeton, NJ. Due to NCATS/NIH funding, we were able to award five (5) deserving young investigators with travel scholarships to attend the conference in 2022 and present at the poster sessions. In 2023, we returned to a virtual format with 397 registrants and 219 participants. We also once again held a poster session with four (4) young investigators - three of which were women and one was African-American. In previous years, over 50% of research attendees were women, 30% of attendees were post-docs or graduate students, and 15% of independent investigators were 5 years or less in their first faculty position. We plan to continue to engage a diverse audience of investigators. RRP is committed to engaging patients, clinicians and/or researchers from underrepresented racial and ethnic groups to broaden participation from these communities at our conference and beyond. The agenda includes research-specific sessions open to all stakeholders as well as a track dedicated to RUNX1-FPD patients and family members. The objective is to promote and drive patient-engaged research forward, with direct patient input in the development and planning of the sessions via our 23-member Research Guided by Patients Committee (RGPC). The research focused portion of the meeting will bring together experts from the fields of hematology, immunology, oncology, cell therapy and basic science who are committed to uncovering the mechanisms underlying the pathogenesis of RUNX1-FPD with the goal of developing therapeutic interventions that impact both the bleeding issues and most importantly the predisposition to malignancy. The audience will include investigators devoted to studying RUNX1, leukemia progression, clonal hematopoiesis, gene editing, and hematopoietic stem cell transplants. It has become increasingly clear through the NHGRI-sponsored natural history study of RUNX1-FPD that immune dysfunction and i...
