Data are presented as n (%).
a
Of which 2 BC patients underwent genetic testing without being registered at the Oncogenetic Clinic in Lund.
b
Genetic testing without findings, including variants of uncertain significance.
c
Positive for a germline pathogenic variant in TP53 (n = 3) or CHEK2 (n = 2).
