Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

2024 Individuals with Dravet syndrome (DS) can have different disease courses, and there are important differences in how seizure and development affect them over time. Identifying the causes of variation within the patient population may be helpful in providing accurate prognosis and developing new treatments. This project will generate broad genetic data with whole genome sequencing on 500 individuals with DS. These genetic analyses will be paired with clinical data using pioneered novel methods to transform clinical information to a format that can be used for computational analysis. Finally, this project is built for data sharing - all biosample data, genomic data, and clinical data will be shared within the DS Community.

2024 Despite recent advances in small molecule drug discovery, the majority of Dravet syndrome (DS) patients remain intractable and non-seizure symptoms are not addressed. This project aims to exploit an alternative therapeutic strategy that has been successful in mouse models: Medial Ganglionic Eminence (MGE) progenitor cell transplantation to restore healthy fast-spiking interneurons in DS patient brains. While transgenic mice have provided invaluable insights into seizures and some comorbidities associated with DS, mice have critical differences in physiology and neuroanatomy compared to humans and thus are not the most appropriate model to test a cell transplantation-based therapy. In contrast, this study will use rabbits, which are larger vertebrates, more similar to humans. The results of this large animal work will strengthen the preclinical foundation for future cell transplantation therapeutic strategies in DS patients.

2024 The scientific understanding of how the SCN1A gene changes brain activity is rapidly evolving. This work will explore whether a brain cell that is integrally important in Dravet syndrome symptomatology has disruptions that lead to specific malfunctions. This work aims to determine how mutations in the SCN1A gene impact these cells' normally powerful ability to "put the brakes on" the brain when it is too active. We believe that the loss of this "brake" may lead to seizures, and our experiments may yield important clues about how to get it working again.

2023 Development of an AI-powered Dravet Syndrome Ontology. Although a significant amount of data for Dravet syndrome (DS) is available from model organisms and humans, methods to integrate and analyze these disparate data resources are limited in scale and functionality. Artificial intelligence (AI) methods such as ontologies and machine learning (ML) algorithms are ideal for complex analytics over big data to aid in knowledge discovery. Satya Sahoo, PhD has already applied a combined epilepsy ontology and ML approach to analyze data resulting in high accuracy classification models. These findings suggest that AI methods can be used for automated analysis of basic science and clinical literature to compare model systems and humans and indicate new experiments to characterize these relationships. A DSF Research Grant was awarded to Dr. Sahoo to extend the epilepsy ontology specifically for DS that together with ML algorithms can automatically index literature and enable analysis of data.

2023 Cerebellar deficits as mechanisms for motor, cognitive, and social dysfunction in Dravet syndrome. A DSF Research Grant was awarded to William Nobis, PhD to investigate if chronic exposure to the odorant 2-phenylethanol ("rose odor") will decrease mortality and improve neuropsychiatric comorbidities of DS through attenuation of extended amygdalar neuronal activation. Given the long history of odorant therapy in the treatment of seizures, as well as links between the areas of the brain that receive olfactory inputs having a role in control of respiration and seizure-related breathing dysfunction, there is potential for odorants that modulate these circuits to provide a non-invasive, well-tolerated means to decrease seizure-related death. Exciting preliminary data using a mouse model of DS suggests that mortality is reduced by chronic exposure to rose odor, and this study will build on that data to explore the effects on mortality, seizure frequency and comorbidities.

2023 Cerebellar deficits as mechanisms for motor, cognitive, and social dysfunction in Dravet syndrome. In addition to frequent and severe seizures, most people with Dravet syndrome (DS) also suffer life-altering difficulties with coordinated movement/muscle control, autism-associated behaviors, and learning and memory. The cerebellum is a brain region known to be involved in movement, cognition/memory, and social behavior, but is understudied in DS. Preliminary data showed that Purkinje cells are hypo-active in a mouse model of DS. Similar hypoactivity of this cell type causes movement disorders and autism in other neurological diseases. A DSF Research Grant was awarded to Mackenzie Howard, PhD to utilize a novel mouse model of DS that has allowed the study of DS-related genetic mutations in this specific cell type and the link to changes in comorbidities often reported in DS.

2022 Lymphoblast Cell Lines as a Model to Uncover Metabolic Defects in Dravet Syndrome- Dr. Patel and Dr. Knupp work together on this collaborative project to establish lymphoblast cell lines from the blood of patients with Dravet syndrome and their unaffected siblings. This library of cell lines will then be used to investigate alterations in energy metabolism that may impact patients with Dravet syndrome as well as stand as a future resource for investigations of new drugs, diets, and treatment responses.

2023 Genetic Substrates and Physiological Triggers for Autonomic and Cardiac Abnormalities in Dravet Syndrome. Using cellular and animal models, David Auerbach, PhD previously demonstrated that Dravet syndrome (DS) mutations result in electrical disturbances in the heart, and cardiac arrhythmias preceded Sudden Unexpected Death in Epilepsy (SUDEP). Patients DS are at a high risk of SUDEP. A DSF Clinical Research Grant was awarded to Dr. Auerbach to perform detailed ECG analysis in two severe forms of epilepsy (DS & Lennox-Gastaut Syndrome) during specific non-seizure physiological states and investigate the temporal evolution of these measures leading up to and following a seizure, which will foster the future development and validation of ECG markers for cardiac-mediated SUDEP risk in DS patients.

2022 Targeting Molecular Responses to Seizures in Dravet Syndrome- Dr. Wagnon's work previously identified that the gene Npas4 is reduced in a mouse model of Dravet syndrome. This project hypothesized that restoration of high Npas4 expression could ameliorate seizures and other symptoms using viral-mediated delivery of Npas4 to the brain of mice with SCN1A haploinsufficiency.

2022 Ketogenic Diet Modulated Brain Energy Metabolism in Dravet Syndrome- Dr. Thio and Dr. Garbow work together on this collaborative project to better understand the mechanisms whereby the ketogenic diet reduces seizures in Dravet syndrome. They will investigate two metabolic pathways in a genetic mouse model of Dravet syndrome and use neuroimaging techniques to assess these impacts within the brain.

Publication 78
Listed as of 10 September 2026, under deductibility PC.
These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
