Specific Genetic Disorders Many human diseases have a genetic
component. Some of these conditions are under investigation by
researchers at or associated with the National Human Genome
Research Institute (NHGRI). Below you will find a list of
selected genetic, orphan and rare diseases. This list is by no
means comprehensive. If the condition you are looking for is not
listed below, you might be able to find other resources of
information in our listing of other Web sites, Online Health
Resources. Sometimes, physicians are unable to put a name to a
genetic condition. When this happens, physicians will say that a
child or an adult has an undiagnosed rare or genetic condition.

that have no diagnosis, see: - Learning About an Undiagnosed
