Importance: Between 5% and 10% of breast cancer cases are associated with an inherited germline pathogenic or likely pathogenic variant (GPV) in a breast cancer susceptibility gene (BCSG), which could alter local and systemic therapy recommendations. Traditional genetic testing criteria misses a proportion of these cases.
Objective: To evaluate the prevalence and clinicopathological associations of GPVs in 2 groups of BCSGs among an ethnically diverse cohort of women with newly diagnosed breast cancer.
Background: Intersex describes a diversity of individuals with variations in sex characteristics (VSC), reflecting underlying differences in reproductive anatomy, hormones, and/or genes and chromosomes. With a shift towards socially-conscious clinical practices, genetic counsellors (GCs) are increasingly needing to provide comprehensive care to individuals with VSC and their families. However, the current quality of training provided to genetic counsellors on intersex health is unclear.

We investigated HR deficiency (HRD)-associated mutational signatures and second hits in tumor DNA from familial BC cases. No candidates genes were associated with HRD in 38 probands previously tested negative with gene panels.
