This photograph shows a GeneChip loaded with RNA from a single patient. The GeneChip will then be processed in the GeneChip fluidics station to attempt to identify the effects of mutations in genes that cause their autoinflammatory disease. The principal investigator for this work is Daniel L. Kastner, M.D., Ph.D., NIAMS Clinical Director and Chief of the Genetics and Genomics Branch.Source: National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Image Gallery
