This conference brings together individuals active in rare diseases and/or orphan drugs across areas of healthcare, research, patient advocacy and public policy. Dr. Pearce presented on the use of animal models for rare diseases and the integration of natural histories into employee health records for a more accurate diagnosis of rare diseases.
August 2017 Drs. David Pearce, Benson Hsu and Emily Griese authored a commentary published in South Dakota Medicine discussing the innovative infrastructure of the Sanford Data Collaborative, a first-of-its-kind health care data sharing initiative to evaluate and transform health care delivery. “Data sharing: leading data-driven population health
August 2017 Drs. David Pearce and Attila Kovacs co-authored a research article published in the Journal of Molecular Neuroscience investigating the feasibility of high-content drug screening on neurons cultured from mice genetically modified to model Juvenile Batten Disease. "Pharmacological effects of ceroid lipofuscin and neuronal structure in Cln3 ?ex7/8 mouse brain cultures".
July 2017 Dr. David Pearce led a collaborative research article with Drs. Alexei Savinov, Attila Kovacs, and Jill Weimer published in Biochimica et Biphysica Acta investigating systemic effects such as infertility and immune dysfunction due to ataxia telangiectasia using a novel porcine model.

June 2017 Dr. David Pearce co-authored a clinical research article published in JAMA Opthalmology detailing clinical, electrophysiologic and genetic features across patients with CLN3 Batten disease-associated retinal degeneration. "Detailed clinical phenotype and molecular genetic findings in CLN3-associated isolated retinal degeneration."
May 2017 Drs. David Pearce and Jill Weimer published a research article in PLoS One characterizing a new mouse model of Cln2-infantile Batten disease which can be used for preclinical screening of nonsense suppression drugs. "A tailored mouse model of CLN2 disease: A nonsense mutant for testing personalized therapies."
April 2017 Drs. David Pearce and Attila Kovács published a research article in the Journal of Cellular Biochemistry studying novel regulatory function of CLN3 which is mutated in the juvenile-onset form of neuronal ceroid lipofuscinosis, a childhood fatal neurodegenerative disorder. "Role of the lysosomal membrane protein, CLN3, in the regulation of cathepsin D activity."
February 2017,David Pearce, PhD, and Attila Kovacs, PhD, authored a research article titled "Decreased sensitivity of palmitoyl protein thioresterase 1-deficient neurons to chemical anoxia" in the journal Metabolic Brain Disease.  They found that genetic deficiency in CLN1 is associated with impaired neuron mitochondrial function and may contribute to the pathogenesis of infantile neuronal ceroid lipofuscinosis. 
November 2016, Dr. Pearce's laboratory published a paper entitled "Decreased sensitivity of palmitoyl protein thioesterast 1-deficient neurons to chemical anoxia" in the Journal Metabolic Brain Disease.
