Study Details

Study Description

Brief Summary

To evaluate immune function in BRCA1/2 mutation carriers without cancer, specifically to determine whether immune function in healthy individuals with germline loss of function BRCA1/2 mutations, impacts overall immune health and fitness.

Outcome Measures

Primary Outcome Measures

  1. To evaluate immune function in female BRCA1/2 mutation carriers without cancer following seasonal influenza vaccination [2 years]

    Analysis of the primary objective will depend on determination of the strain-specific neutralizing antibody titer change from day 0 to the last study visit, performed as the standard assay as described by the World Health Organization (WHO).

Secondary Outcome Measures

  1. Exploratory analysis- phenotypic evaluation of B cell [2 years]

    Phenotypic evaluation of B and T cell responses to vaccine at each timepoint. Phenotypic analysis involves flow cytometry on peripheral blood mononuclear cells (PBMC) from all subjects (10 mL blood per subject).

  2. Exploratory analysis - transcriptional evaluation [2 years]

    Transcriptional evaluation of B and T cell responses to vaccine on day 7-10 timepoint. Transcriptional analyses including quantitative real-time PCR (RT-qPCR) and RNA sequencing (RNAseq) may be performed on a subset of the study subjects on the day 7-10 time point.
