MedlinePlus invites patient support and advocacy groups to provide feedback on genetics-related content on the website to help ensure that it is up-to-date and relevant for the patient community. This feedback helps us provide high-quality information about genetics to patients, their families, and the general public.

We hope this page will help answer questions you may have about the process.

What is MedlinePlus?

MedlinePlus is an online health information resource for patients and their families and friends that provides easy-to-understand pages on a variety of health and wellness topics. It is a service of the National Library of Medicine (NLM), which is part of the National Institutes of Health (NIH).

NLM's Genetics Home Reference became part of MedlinePlus in 2020. MedlinePlus Genetics provides information about genetic conditions and the genes or chromosomes related to those conditions. Please see Learn about MedlinePlus and About MedlinePlus Genetics to learn more.

What genetics information is on MedlinePlus?

• Within MedlinePlus Genetics, the main page types are genetic condition summaries and gene summaries.
  • Condition summaries provide in-depth information about the major features of the condition, the condition's genetic basis, and its pattern of inheritance.
  • Gene summaries provide the official name and symbol of a gene, an explanation of its normal function, and the health implications of variations in the gene. Gene summaries are not typically included in this update process.
• Health Topics highlight the symptoms, causes, treatment, and prevention of health conditions. Each page has an easy-to-read overview and displays links to information from NIH and other authoritative sources.
• Other sections of MedlinePlus may include genetics information, but because the content is maintained independently, these sections are not part of this update process.
  • The Medical Encyclopedia includes articles about many health and wellness topics, including genetic conditions. This content is licensed from A.D.A.M.
  • Medical Tests describe tests used to screen for, diagnose, and guide the treatment of various health conditions. Some of these tests are gene-based.

Why is there sometimes more than one page about the same topic?

Prior to the merging of Genetics Home Reference, MedlinePlus provided select information about genetics and genetic health conditions. These pages differ in scope and complexity than the MedlinePlus Genetics pages. To serve user needs at all levels, it was decided that all the content would be maintained. In the future, MedlinePlus plans to coordinate the content so there is less redundancy.

What kind of feedback are you looking for?

We ask that you look over the proposed Genetics condition summary and/or Health Topic and review it for accuracy. All suggestions for improvement are welcome. Please review the following information to be sure your suggested change relates to information in MedlinePlus's scope:
