NOTE:
OMIM is intended for use primarily by physicians and other professionals concerned with genetic disorders, by genetics researchers, and by advanced students in science and medicine. While the OMIM database is open to the public, users seeking information about a personal medical or genetic condition are urged to consult with a qualified physician for diagnosis and for answers to personal questions. Further, please be sure to click through to omim.org for the very latest, as they are continually updating data.

OMIM is a compendium of human genes and genetic phenotypes. The full-text, referenced overviews in OMIM contain information on all known Mendelian disorders and over 12,000 genes. OMIM is authored and edited at the McKusick-Nathans Institute of Genetic Medicine, Johns Hopkins University School of Medicine, under the direction of Dr. Ada Hamosh. This database was initiated in the early 1960s by Dr. Victor A. McKusick as a catalog of Mendelian traits and disorders, entitled Mendelian Inheritance in Man (MIM).

The OMIM data are separated into three separate tracks:

OMIM Allelic Variant SNPs
Variants in the OMIM database that have associated dbSNP identifiers.

OMIM Genes
The genomic positions of gene entries in the OMIM database. The coloring indicates the associated OMIM phenotype map key.

OMIM Phenotypes - Gene Unknown
Regions known to be associated with a phenotype, but for which no specific gene is known to be causative. This track also includes known multi-gene syndromes.
