Analysis of the gene panel
The laboratory will carry out the TUMOSPEC gene panel analysis at the same time as the BRCA1 and BRCA2 analysis and will return a negative (no mutation) or positive (presence of a mutation allowing enrolment of family members) result.
Other: Genetic testing
A panel of 24 genes, chosen in advance by a steering committee, will be tested as the same time as the BRCA1/2 genes, at one of the usual BRCA1/2 analysis laboratories belonging to the same network and participating in the study.
- Penetrance estimation of the mutations identified in the gene panel [ Time Frame: 2 years ]The primary outcome is to obtain unbiased penetrance estimates of the mutations identified in the gene panel (about 20 genes), which will be analysed by the molecular diagnostic laboratories at the same time as the BRCA1 and BRCA2 genes
- The results for the whole panel sequencing will be formatted to be used by all laboratories allowing the subsequent centralisation of the data. [ Time Frame: 2 years ]This outcome will allow to establish a procedure for centralising homogeneous genomic sequencing data produced by the molecular diagnostics laboratories
- Relative risk will be determined by the ratio of calculated cancer incidence in mutated and non-mutated families for this gene. [ Time Frame: 2 years ]To determine the deleterious nature of a variant the gene panels will be analysed by the various molecular diagnostics laboratories and we will estimate the relative risk by the ratio of calculated cancer incidence in mutated and non-mutated families for this gene.
