The KRAS-variant is an inherited genetic mutation that is frequently found in women with advanced endometriosis and is associated with an increased risk of certain types of cancers.1-7

Endometriosis, which affects approximately 1 in 10 girls and women in the U.S., can be a painful condition which may impact a woman’s fertility.

The KRAS-variant is the only inherited genetic variant associated with developing endometriosis,8,9 and women with this genetic mutation are at risk of especially aggressive forms of endometriosis, meaning it has the potential to be treatment-resistant and associated with infertility.

MiraKind’s research is focused on better understanding the lifestyle and environmental factors that impact endometriosis, as well as cancer risk for KRAS-variant individuals so that they may make informed decisions to protect their health. Learn more about MiraKind’s open or future research studies that may be relevant to you.


Our goal at MiraKind is to conduct research studies which will help identify the most effective strategies for KRAS-variant women with endometriosis to manage their condition and reduce their future cancer risk.

If you have endometriosis, or a family history of endometriosis and/or cancer, please enroll in a MiraKind study. Our current study aims to identify which medicines work best for managing endometriosis and minimizing future cancer risk. Being a study participant is FREE, and if eligible you can choose to get your KRAS-variant results for $195.


The MiraKind community brings together individuals with the KRAS-variant to share their stories, learn from one other, and offer support.  Learn more.
