About Us


Our mission is to educate individuals about the KRAS-variant, in order to prevent disease by expanding access to, and fostering understanding of our unique class of genetic biomarkers.



MiraKind is a nonprofit organization founded by Joanne Weidhaas, MD, PhD, in 2013, in order to find answers for patients who have the KRAS-variant and to advance the understanding of other variants like it.

Dr. Weidhaas co-discovered the KRAS-variant in 2006, and first identified the KRAS-variant as an inherited genetic variant associated with an increased risk of lung cancer 1. Soon after, she led studies finding that the KRAS-variant was also associated with an increased risk of ovarian cancer, and triple negative breast cancer 2,3.

As a cancer doctor, Dr. Weidhaas believed that with the knowledge of increased genetic risk, came the responsibility of figuring out how best to help people with these types of genetic risk variants. Dr. Weidhaas understood that the KRAS-variant was a new type of variant, and knew that working with the patients to help find strategies to mitigate their cancer risk was the best way to do this.

In 2012, Dr. Joanne Weidhaas led a study called “Hormones, the KRAS-variant and Breast Cancer Risk”, which evaluated the role estrogen plays in cancer risk for people with the KRAS-variant 7. The findings of this study led to the discovery that estrogen played a protective role against developing breast cancer in women with the KRAS-variant, and showed how truly unique variants like the KRAS-variant are. Dr. Weidhaas believes that these findings would not have come about if it wasn’t for the generous participation of the women in the 2012 study.

Dr. Weidhaas founded MiraKind in order to continue working with the patient community to search for answers and solutions for people with the KRAS-variant and other genetic variants like it.

Joanne Weidhaas, M.D., Ph.D.

Dr. Weidhaas is an oncologist and scientist who is passionate about improving patients' lives through research. In 2006, Dr. Weidhaas, MD, PhD, physician-scientist and at the time the head of the breast radiation oncology service at Yale University, co-discovered the KRAS-variant, a new type of genetic marker with broad implications in cancer and human health 1. The KRAS-variant itself has significant implications for women’s health 7.

Despite her discovery’s significance, Dr. Weidhaas recognized the need to educate people directly about the KRAS-variant, and other variants like it, which led her to found MiraKind. She continues her work as head of translational research and vice-chair of radiation oncology at UCLA. Her goal is to continue to provide meaningful discoveries that reach both patients and their doctors.
