reviewed 715 male breast cancer patients who underwent germline multi-gene panel testing and found that pathogenic variants in CHEK2 (OR = 3.7, p = 6.24 × 10-24) and PALB2 (OR = 6.6, p = 0.01) were both significantly associated with breast cancer risk in men (40). Here, PALB2 is linked to breast carcinoma.
