    The path forward: 2015 International Children's Tumor Foundation conference on neurofibromatosis type 1, type 2, and schwannomatosis
    (Wiley, 2017-06) Blakely, Jaishri O.; Bakker, Annette; Barker, Anne; Clapp, Wade; Ferner, Rosalie; Fisher, Michael J.; Giovannini, Marco; Gutmann, David H.; Karajannis, Matthias A.; Kissil, Joseph L.; Legius, Eric; Lloyd, Alison C.; Packer, Roger J.; Ramesh, Vijaya; Riccardi, Vincent M.; Stevenson, David A.; Ullrich, Nicole J.; Upadhyaya, Meena; Stemmer-Rachamimov, Anat; Pediatrics, School of Medicine
    The Annual Children's Tumor Foundation International Neurofibromatosis Meeting is the premier venue for connecting discovery, translational and clinical scientists who are focused on neurofibromatosis types 1 and 2 (NF1 and NF2) and schwannomatosis (SWN). The meeting also features rare tumors such as glioma, meningioma, sarcoma, and neuroblastoma that occur both within these syndromes and spontaneously; associated with somatic mutations in NF1, NF2, and SWN. The meeting addresses both state of the field for current clinical care as well as emerging preclinical models fueling discovery of new therapeutic targets and discovery science initiatives investigating mechanisms of tumorigenesis. Importantly, this conference is a forum for presenting work in progress and bringing together all stakeholders in the scientific community. A highlight of the conference was the involvement of scientists from the pharmaceutical industry who presented growing efforts for rare disease therapeutic development in general and specifically, in pediatric patients with rare tumor syndromes. Another highlight was the focus on new investigators who presented new data about biomarker discovery, tumor pathogenesis, and diagnostic tools for NF1, NF2, and SWN. This report summarizes the themes of the meeting and a synthesis of the scientific discoveries presented at the conference in order to make the larger research community aware of progress in the neurofibromatoses.

    RAS Signaling Gone Awry in the Skin: The Complex Role of RAS in Cutaneous Neurofibroma Pathogenesis, Emerging Biological Insights
    (Elsevier, 2023) Rhodes, Steven D.; McCormick, Frank; Cagan, Ross L.; Bakker, Annette; Staedtke, Verena; Ly, Ina; Steensma, Matthew R.; Lee, Sang Y.; Romo, Carlos G.; Blakeley, Jaishri O.; Sarin, Kavita Y.; Pediatrics, School of Medicine
    Cutaneous neurofibromas (cNFs) are the most common tumor in people with the rasopathy neurofibromatosis type 1. They number in hundreds or even thousands throughout the body, and currently, there are no effective interventions to prevent or treat these skin tumors. To facilitate the identification of novel and effective therapies, essential studies including a more refined understanding of cNF biology and the role of RAS signaling and downstream effector pathways responsible for cNF initiation, growth, and maintenance are needed. This review highlights the current state of knowledge of RAS signaling in cNF pathogenesis and therapeutic development for cNF treatment.

    The seventh international RASopathies symposium: Pathways to a cure-expanding knowledge, enhancing research, and therapeutic discovery
    (Wiley, 2022) Kontaridis, Maria I.; Roberts, Amy E.; Schill, Lisa; Schoyer, Lisa; Stronach, Beth; Andelfinger, Gregor; Aoki, Yoko; Axelrad, Marni E.; Bakker, Annette; Bennett, Anton M.; Broniscer, Alberto; Castel, Pau; Chang, Caitlin A.; Cyganek, Lukas; Das, Tirtha K.; den Hertog, Jeroen; Galperin, Emilia; Garg, Shruti; Gelb, Bruce D.; Gordon, Kristiana; Green, Tamar; Gripp, Karen W.; Itkin, Maxim; Kiuru, Maija; Korf, Bruce R.; Livingstone, Jeff R.; López-Juárez, Alejandro; Magoulas, Pilar L.; Mansour, Sahar; Milner, Theresa; Parker, Elisabeth; Pierpont, Elizabeth I.; Plouffe, Kevin; Rauen, Katherine A.; Shankar, Suma P.; Smith, Shane B.; Stevenson, David A.; Tartaglia, Marco; Van, Richard; Wagner, Morgan E.; Ware, Stephanie M.; Zenker, Martin; Pediatrics, School of Medicine
    RASopathies are a group of genetic disorders that are caused by genes that affect the canonical Ras/mitogen‐activated protein kinase (MAPK) signaling pathway. Despite tremendous progress in understanding the molecular consequences of these genetic anomalies, little movement has been made in translating these findings to the clinic. This year, the seventh International RASopathies Symposium focused on expanding the research knowledge that we have gained over the years to enhance new discoveries in the field, ones that we hope can lead to effective therapeutic treatments. Indeed, for the first time, research efforts are finally being translated to the clinic, with compassionate use of Ras/MAPK pathway inhibitors for the treatment of RASopathies. This biannual meeting, organized by the RASopathies Network, brought together basic scientists, clinicians, clinician scientists, patients, advocates, and their families, as well as representatives from pharmaceutical companies and the National Institutes of Health. A history of RASopathy gene discovery, identification of new disease genes, and the latest research, both at the bench and in the clinic, were discussed.
