As shown in numerous independent studies, women with the KRAS-variant are at an increased risk of developing breast and ovarian cancer, non-small cell lung cancer, and multiple primary breast cancer. Recent data now indicates that changing estrogen levels i.e. estrogen withdrawal, can trigger cancer in women with the KRAS-variant. Knowing a woman’s KRAS-variant status is an additional piece of critically important information to help direct decisions for estrogen management as well as screening.
MiraDx has a program to confirm a diagnosis of Ataxia Telangiectasia in children, based on work from the Gatti laboratory spanning over 40 years.
The KRAS-variant is a biomarker that has been shown to significantly predict sensitivity and resistance to specific cancer treatments, regardless of tumor type. This information can subgroup patients into responders or non-responders for therapies being used today as well as developing immunotherapies. Currently work is ongoing to develop the best approaches to treat cancer patients with the KRAS-variant, as well as other mutations in this class. This information is currently especially critical for individuals with metastatic cancer, as this information should inform choices for palliative therapies.
Currently, there are no biomarkers applied before radiation therapy treatment to identify patients who have different sensitivities to radiation therapy. As this treatment is used in over 67% of cancer patients there is a strong need. MiraDx is developing a panel of such biomarkers, using germ-line, functional biomarkers such as the KRAS-variant.
Despite the dangers of the KRAS-variant mutation, few doctors have heard of it. But one researcher is trying to change that.
