About Us


Our mission is to educate individuals about our unique class of genetic biomarkers, to advance research about them in order to find ways to prevent and better treat disease, and to help enable access to their meaningful applications.



MiraKind is a nonprofit organization founded by Joanne Weidhaas, MD., PhD., in 2013, after the discovery of the KRAS-variant, the first discovered of a unique class of genetic biomarkers with dramatic implications for cancer risk, prevention, and treatment.

Dr. Weidhaas co-discovered the KRAS-variant in 2006, and soon thereafter found that the variant was associated with an increased risk of lung cancer,1 ovarian cancer, and triple negative breast cancer.2,3 After additional studies found that women with the KRAS-variant were at risk of multiple primary cancers,4 Dr. Weidhaas established MiraKind and set its mission to find ways to best help people with the increased risks presented by this variant.

As more and more studies of the KRAS-variant were completed, it became clear that by using this variant and variants like it, was possible to identify specific cancer treatments that would work best, both for response as well as minimizing side effects.

Since the founding of MiraKind in 2006, Dr. Weidhaas has discovered hundreds of additional variants like the KRAS-variant. MiraKind has expanded its mission to serve the entire community of individuals who carry these important biomarkers.
