From Johns Hopkins University-- "A comprehensive, authoritative, and timely compendium of human genes and genetic phenotypes... OMIM focuses on the relationship between phenotype and genotype. It is updated daily, and the entries contain copious links to other genetics resources."
This site was created by John H. McDonald, Ph.D, who teaches in the biological sciences department at the University of Delaware. The material was also published as a book and he lists citation information (including corresponding page numbers in the book) at the bottom of each page.
"Our hope is to enable you to discover new research articles important to you, no matter where they are published... You should be able to simply come to this site or open our app, and instantly see all the new research that you should know about."
