  1. Shown is the distribution of genotypes defined by the observed AIB1 glutamine repeat alleles (n [%]) in cases and controls, and in cases categorized by family history and by BRCA1 and BRCA2 germline mutation status. aOne case, with the 29/29 repeats AIB1 genotype, had a germine mutation in BRCA1 and a germline mutation in BRCA2 [9].
