Online Mendelian Inheritance in Man (OMIM)

Online Mendelian Inheritance in Man (OMIM) is a continuously updated, freely accessible catalog of human genes and genetic disorders. It documents gene-phenotype relationships, inheritance patterns, and molecular details, serving as a key reference for clinicians, researchers, and genetic counselors.

What is Online Mendelian Inheritance in Man (OMIM)?

Online Mendelian Inheritance in Man (OMIM) is a continuously updated, freely accessible catalog of human genes and genetic disorders. It records relationships between genes and the conditions, or phenotypes, they are linked to, along with inheritance patterns and molecular detail.

The resource functions as an authoritative reference, summarizing and citing the research literature on the genetic basis of disease.

Why does OMIM matter?

OMIM serves clinicians, researchers, and genetic counselors who need reliable information about how specific genes relate to inherited conditions. It helps in interpreting genetic test results and understanding disease mechanisms.

As genetic and genomic medicine grows, a curated reference like OMIM supports diagnosis of rare disorders and underpins research into the molecular causes of disease, sitting firmly in the research and clinical-genetics domain rather than procedural care.
