This is a completed observational study registration that enrolled 266 Hispanic/Latino women with breast cancer to collect saliva samples and medical/family history for BRCA mutation prevalence research. No results, outcomes, or genetic findings are reported in this registry record.

Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
This is a completed observational registry study with no posted results; it describes enrollment and biospecimen collection methodology only, without outcome data or analysis.
As stated by the source record.
Quoted from the source exactly as published.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no key findings. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT01251900). This is a study registration, not published results. Lead sponsor: National Cancer Institute (NCI). Recruitment status: COMPLETED. Study type: OBSERVATIONAL. Enrollment: 266 participants (ACTUAL). Conditions: Breast Neoplasms. Primary outcome measures: Collection of saliva from 2000 probands , Every six months. Brief summary: Background: \- BRCA1 and BRCA2 gene mutations have been linked to a higher risk of developing breast cancer and other cancers, and may be associated with types of breast cancer that are more difficult to treat and more likely to recur. New cancer treatments are being developed specifically to treat individuals who have these gene mutations. However, more information is needed about the prevalence of these mutations in minority populations, including Hispanic/Latino populations. To study these populations, researchers are interested in collecting genetic material (DNA) and medical history information from Hispanic/Latino women who have been diagnosed with breast cancer. Objectives: \- To collect saliva samples and medical and family history information from Hispanic/Latino women with breast cancer. Eligibility: \- Hispanic/Latino women at least 18 years of age who have been diagnosed with breast cancer. Design: * Participants will complete a questionnaire with information about place of birth, languages spoken by parents and grandparents, and information about their breast cancer diagnosis. * Participants will provide a saliva sample (2 to 3 tablespoons) for analysis. * No treatment will be provided as part of this protocol.
