Individual differences in breast size are a conspicuous feature of variation in human females and have been associated with fecundity and advantage in selection of mates. To identify common variants that are associated with breast size, we conducted a large-scale genotyping association meta-analysis in 7,169 women of European descent across 3 independent sample collections with digital or screen film mammograms. The samples consisted of the Swedish KARMA, LIBRO-1 and SASBAC studies genotyped on iCOGS, a custom illumina iSelect genotyping array comprising of 211,155 single nucleotide polymorphisms (SNPs) designed for replication and fine mapping of common and rare variants with relevance to breast, ovary and prostate cancer. Breast size of each subject was ascertained by measuring total breast area (mm2) on a mammogram. We confirm genome-wide significant associations at 8p11.23 (rs10086016, P = 1.3 × 10−14) and report a new locus at 22q13 (rs5995871, P = 3.2 × 10−8). The latter region contains the MKL1 gene, which has been shown to impact endogenous estrogen-receptor α transcriptional activity and is recruited on estradiol-sensitive genes. We also replicated previous GWAS findings for breast size at four other loci. A new locus at 22q13 may be associated with female breast size.
