We observed significant differences of VNTR genotypes between control and BRCA1+ group (P < 0.0001) and BRCA2+ group (P = 0.0042) but not BRCAx group (P = 0.2185), and the differences were significant between control and cancer-affected BRCA1+ cases (P < 0.0001) and BRCA2+ cases (P = 0.0092) but not cancer-affected BRCAx cases (P = 0.4251). The gene discussed is BRCA1; the disease is cancer.
