BRCA1/2 mutation frequencies in patients with TNBC and non-TNBC

	TNBC (N = 192)	Non-TNBC (N = 331)	P a
Mutation status	n (%)	n (%)
Carriers	73 (38.0)	52 (15.7)	< 0.0001 b
BRCA1	71 (37.0)	34 (10.3)	< 0.0001 c
BRCA2	2 (1.0)	18 (5.4)	NSd
Non-carriers	119 (62.0)	279 (84.3)

P values marked in bold are statistically significant

NS non-significant, TNBC triple-negative breast cancer
