摘要: Decreased sequencing costs have led to an explosion of genetic and genomic data. These data revealed thousands candidate human disease variants. Establishing which variants cause phenotypes diseases, however, has remained challenging. Significant progress been made, including advances by the National Institutes Health (NIH)-funded Undiagnosed Diseases Network (UDN). However, 6000-13,000 additional genes remain be identified. The continued discovery rare diseases their underpinnings provides benefits affected patients, whom there are more than 400 million worldwide, also understanding mechanisms common diseases. Platforms employing model organisms enable novel gene-disease relationships, help establish variant pathogenicity, often lead exploration underlying pathophysiology that suggest new therapies. Model Organism Screening Center (MOSC) UDN is a unique resource dedicated utilizing informatics functional studies in organisms, worm (Caenorhabditis elegans), fly (Drosophila melanogaster), zebrafish (Danio rerio), aid diagnosis. MOSC directly contributed diagnosis challenging cases, multiple patients with complex, multi-organ phenotypes. In addition, framework for how basic scientists clinicians can collaborate drive diagnoses. Customized experimental plans take into account patient presentations, specific variant(s), appropriateness each organism analysis. generates bioinformatic tools reagents wider scientific community. Two elements instrumental its success (1) multidisciplinary teams expertise bioinformatics genetics, (2) ongoing communication clinical teams. Here we provide position statement regarding central role genes, advocate continuation expansion MOSC-type research entities as Organisms (MON) funded through grant applications submitted NIH, family groups focused on other philanthropic organizations, industry partnerships, sources support.
