GARD knows that one of the biggest challenges patients and their families face when learning about rare and genetic diseases is understanding the complex genetics and medical terms used by the medical and scientific communities. We have created this glossary of terms to help patients and their families better understand the genetics and medical terms that are used on our website.

Would you like to suggest a term? We would like to hear from you.
