BRCA1 and BRCA2 Mutation in Romanian Population: a Study of Genotype - Phenotype Correlation at Diagnosis With Prospective Disease Outcome and Survival

Alexandru Eniu

Status: Completed

Conditions: To Determine the Prevalence, Penetrance of BRCA1 and BRCA2 Mutations in Romanian Womens With Breast or Ovarian Cancer

Treatments: Genetic: NGS BRCA 1 and BRCA 2 full sequencing; Genetic: Multiplex ligation-dependent probe amplification (MPLA) BRCA1 BRCA2

Study type: Observational

Funder types: Other

Identifiers

NCT02317120

D0810C00088

About

Primary objective To determine BRCA1 and BRCA2 variants in 250 Romanian women with breast/ovarian cancer selected for likeliness to harbor germline mutations in these genes by specific criteria for high-risk status including age at disease onset.

Secondary objective Considering the fact that BRCA testing is not a routine procedure in Romania and mutation prevalence varies in different populations, we intend to look for the founder mutation in our population, running full BRCA genes sequencing to a representative population sample. This would allow a more targeted approach to real-life practice and would ensure personalized solutions for every patient in need.

Enrollment: 250 patients

Sex: Female

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Categories of patients to be recruited for complete sequencing of all BRCA1 and BRCA2 exons are subjects who have been diagnosed with breast or ovarion cancer and who are:
