Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who carry specific gene variants associated with cancer risk and their relatives.

Probably not a fit

Patients who are minors or those without a signed consent form will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The COVAR project aims to classify variants of unknown significance (VUS) in the BRCA1, BRCA2, and other cancer-related genes to enhance genetic counseling for patients and their families. By utilizing a comprehensive database of genetic tests, the study seeks to provide real-time insights into the implications of these variants for cancer predisposition. Participants will provide saliva samples for genetic analysis, which will help determine the clinical management strategies, including potential prophylactic surgeries for at-risk individuals.

Why it matters

Potential benefit: If successful, this study could lead to improved risk assessment and management strategies for patients with genetic predispositions to cancer.

How similar studies have gone: Other studies have shown success in classifying genetic variants, indicating that this approach is promising and builds on existing knowledge.

Inclusion Criteria:

Index cases:

* A person carrying a variant of interest in a gene analyzed in a diagnostic setting by one of the laboratories within the Genetics and Cancer Group (GGC)-Unicancer network, classified as class 3, 4 or hypomorphic class 5, and selected by the national expert group for the gene concerned.
* Age ≥ 18 years.
* Signed written inform consent "index case"

Related parties:

* Any relative of an index case with cancer
* Any relative without cancer related to an index case, selected by the investigators, according to family structure and degree of related compared to the index case
* For class 4 and hypomorphic class 5 variants; relatives currently undergoing analysis or having already obtained a test result for the variant of interest as part of clinical care.
* Age ≥ 18 years
* Information and signature of the informed consent "selected relatives"
