The investigators will recruit and enroll individuals that may have the KRAS-variant or other microRNA binding site mutations to join registry studies. The investigators will allow individuals to obtain their results through a physician at the completion of the studies. The investigators current focus is breast cancer.

Condition Intervention
Genetic: KRAS-variant

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 10 Years
Official Title: Clinical Validation of the Role of microRNA Binding Site Mutations in Cancer Risk, Prevention and Treatment

Further study details as provided by MiraKind:

Primary Outcome Measures:
Measuring the prevalence of the KRAS-variant in certain populations Prevalence of the KRAS-variant in BRCA negative breast cancer patients [ Time Frame: 1 year ] [ Designated as safety issue: No ]
The Prevalence of the KRAS-variant will be determined in specific populations, such as women with drug resistant endometriosis, or BRCA negative breast cancer. The prevalence will be compared to extensive data on the expected and known prevalence of the KRAS-variant in non-diseased populations. Statistical significance will be determined by Chi-squared analysis.

Comparing the impact of interventions in KRAS-variant versus non-KRAS variant populations [ Time Frame: 1 year ] [ Designated as safety issue: No ]
We will compare the impact of specific treatment approaches for example in women with the KRAS-variant and double primary breast cancer, versus the interventions used in non-KRAS-variant double primary breast cancer patients.

Secondary Outcome Measures:
The impact of lifestyle factors on cancer risk for KRAS-variant patients [ Time Frame: 10 years ] [ Designated as safety issue: No ]
Individuals with the KRAS-variant will be prospectively followed, and lifestyle factors will be associated with changes in health, including cancer development. Our goal is to compare baseline characteristics between individuals with the KRAS-variant who do, versus do not, develop cancer, for example.

Biospecimen Retention: Samples Without DNA
DNA will be isolated from the submitted sample and kept with permission for additional studies.

Estimated Enrollment: 15000
Study Start Date: September 2014
Estimated Study Completion Date: September 2025
Estimated Primary Completion Date: September 2025 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Family Registry
For individuals identified with the KRAS-variant. Patients will be prospectively followed to determine the impact of lifestyle on disease risk.
Genetic: KRAS-variant
Participant in these studies will be tested for the KRAS-variant
Pregnancy Associated Breast Cancer
Women with PABC will be tested for the KRAS-variant, and women with and without this mutation will be compared.
Genetic: KRAS-variant
Participant in these studies will be tested for the KRAS-variant
KRAS-variant BRCA negative Breast Cancer
Women with breast cancer who are BRCA negative will be tested for the KRAS-variant, to determine the associations as well as the prevalence.
Genetic: KRAS-variant
Participant in these studies will be tested for the KRAS-variant
Double primary breast cancer
Women with multiple primary breast cancer will be tested for the KRAS-variant and compared between those with this mutation and those without.
Genetic: KRAS-variant
Participant in these studies will be tested for the KRAS-variant

Detailed Description:
The investigators have identified germ-line microRNA binding site mutations that predict an increased risk of cancer, endometriosis and associated infertility, and unique tumor biology and response to treatment. The goal of this protocol is to further determine the mechanisms of these mutations, such as the KRAS-variant, and their associations with human health, such as cancer. The investigators will collect saliva samples from individual patients who are eligible and choose to enroll in these studies, to test for the KRAS-variant and/or other mutations under study. With specific permission, the investigators will keep excess DNA to further investigate and discover additional similar mutations. The investigators purpose is to have participants answer questionnaires about lifestyle factors in an ongoing manner, to understand the impact of different factors on cancer risk for patients with these mutations.
