Abstract
Online Mendelian Inheritance in Man (OMIM) is a comprehensive compendium of information on human genes and genetic disorders, with a particular emphasis on the interplay between observed phenotypes and underlying genotypes. This unit focuses on the basic methodology for formulating OMIM searches and illustrates the types of information that can be retrieved from OMIM, including descriptions of clinical manifestations resulting from genetic abnormalities. This unit also provides information on additional relevant medical and molecular biology databases. A basic knowledge of OMIM should be part of the armamentarium of physicians and scientists with an interest in research on the clinical aspects of genetic disorders. Curr. Protoc.

Figure 1.2.1 Search results from the OMIM query, returning all OMIM entries that pertain to the deleted in colorectal carcinoma (DCC) gene. The first entry in the list is the main entry discussing DCC. View Image -
Figure 1.2.2 The detailed view of the DCC entry in OMIM. Details on the various sections of this view can be found in the main text. View Image -
Figure 1.2.3 The OMIM Gene Map, centered on the position of the DCC gene at chromosomal location 18q21.2. The contents of the various columns are described in the Guidelines for Understanding Results. View Image -
Figure 1.2.4 A tabular view of all known allelic variants in the DCC gene, leading to a variety of clinical outcomes. Here, five allelic variants are shown: one for somatic colorectal cancer, one for somatic esophageal carcinoma, and three for congenital mirror movements. For each, the actual mutation (either at the nucleotide or protein level) is given in the third column. View Image -
Figure 1.2.5 A detailed description of each of the known allelic variants in the DCC gene. The text in this part of the OMIM entry deals specifically with each of these allelic variants, providing information on how these mutations were found, implications of these mutations for basic cellular processes, and information on the ultimate clinical outcome in individuals carrying these mutations.
