COVID-19 is an emerging, rapidly evolving situation. Get the latest public health information from CDC: https://www.coronavirus.gov . Get the latest research from NIH: https://www.nih.gov/coronavirus .

As of October 1, 2020, the National Library of Medicine (NLM) will no longer offer Genetics Home Reference as a stand-alone website. Instead, much of the content from Genetics Home Reference has been transferred to MedlinePlus, the NLM’s flagship website for health information for patients, families, and the general public.

Please visit MedlinePlus Genetics (https://medlineplus.gov/genetics) to access genetics information and learn more about this change.
