MedGen: Your search engine for human medical genetics


MedGen is a free, comprehensive resource for one-stop access to essential information on phenotypic health topics related to medical genetics as collected from established high-quality sources. It integrates terminology from multiple primary ontologies (or nomenclatures) to facilitate standardization and more accurate results from search queries.

Some things you can do in MedGen:

Discover GTR at AMP 2018 (Nov 1-3)


Starting this Thursday, November 1st, NCBI staff from projects like ClinVar, GTR, MedGen, Medical Genetics Summaries and OSIRIS will be ready to hear your feedback at the Association for Molecular Pathology (AMP) 2018 Annual Meeting & Expo in San Antonio, Texas. Come to booth #1810 and tell us how to make our resources better for you or ask questions about how to participate and use these resources!

Staff will also present on their current work at AMP 2018. We will present our analyses of current GTR tests and discuss how GTR data aims to reflect the current genetic testing landscape.

Below is a sneak peek on two different presentations to learn about “The NIH Genetic Testing Registry (GTR): Test Methodologies as a Sensor of the Precision Medicine Environment”:

  • Poster TT046 – Friday, November 2 from 2:30 – 3:30 PM
  • Technical Topics Platform Presentation – Saturday, November 3 from 7:45 – 8:00 AM

May 2 webinar: Using NCBI’s MedGen in Clinical Practice


Join us next Wednesday, May 2, 2018, 12:00 PM – 12:30 PM EDT for a webinar on MedGen, NCBI’s portal to clinical genetics. We’ll show you how to find information in MedGen on genetic phenotypes, clinical features of disorders, and more. You’ll also learn how to retrieve actionable information such as practice guidelines for a condition and get a list of available genetic tests in GTR, and how to easily access resources like GeneReviews, OMIM and ClinicalTrials.gov, the Genetic and Rare Diseases Information Center, and Medline Plus.

After registering, you will receive a confirmation email with information about attending the webinar. A few days after the live presentation, you can view the recording on the NCBI YouTube channel. You can learn about future webinars on the Webinars and Courses page.

Questions about GTR, ClinVar, or MedGen? Ask us at ASCO 2017!


NCBI will be exhibiting at the ASCO Annual Meeting 2017 from June 2-6.

Exhibit Hall Booth #3046

ASCO attendees can get navigation tips and hands-on help with GTR and ClinVar submissions, take handout materials and meet with Adriana Malheiro, MS* at Booth #3046.

Booth times:

Saturday, June 3 – 9AM–5PM
Sunday, June 4 – 9AM–5PM
Monday, June 5 – 9AM–5PM

*Contact us to schedule a meeting with Adriana Malheiro, MS.

NCBI’s 3 Newest Medical Genetics Resources: GTR, MedGen & ClinVar


GTR_ClinVar_MedGen imageNCBI has three relatively new online resources for information about genetic tests, genetic conditions, and genetic variations:

  • The Genetic Testing Registry, or GTR – a registry of genetic tests for heritable and somatic changes in humans
  • MedGen – a medical genetics portal that focuses on information about medical conditions with a genetic component
  • ClinVar – an archival database that contains reported assertions about the relationship between genetic variations and phenotypes

This blog will provide a very brief overview of the three resources by outlining some of their content features. For a more thorough introduction to the three resources, including the types of information available in each and how to use them, we recommend viewing this approximately hour-long webinar that we conducted in June 2014.
