Early-onset breast cancer (EOBC) causes substantial loss of life and productivity, creating a major burden among women worldwide. We analyzed 1,265,548 Hapmap3 SNPs among a discovery set of 3,523 EOBC incident case and 2,702 population control women aged <=51 years.="" the="" snps="" with="" smallest="" p-values="" were="" examined="" in="" a="" replication="" set="" of="" 3,470="" eobc="" case="" and="" 5,475="" control="" women.="" we="" also="" tested="" eobc="" association="" with="" 19,684="" genes="" by="" annotating="" each="" gene="" with="" putative="" functional="" snps,="" and="" then="" combining="" their="" p-values="" to="" obtain="" a="" gene-based="" p-value.="" we="" examined="" the="" gene="" with="" smallest="" p-value="" for="" replication="" in="" 1,145="" breast="" cancer="" case="" and="" 1,142="" control="" women.="" the="" combined="" discovery="" and="" replication="" sets="" identified="" 72="" new="" snps="" associated="" with="" eobc=""><4x10-8) located="" in="" six="" genomic="" regions="" previously="" reported="" to="" contain="" snps="" associated="" largely="" with="" later-onset="" breast="" cancer="" (lobc).="" snp="" rs2229882="" and="" 10="" other="" snps="" on="" chromosome="" 5q11.2="" remained="" associated=""><6x10-4) after="" adjustment="" for="" the="" strongest="" published="" snps="" in="" the="" region.="" thirty-two="" of="" the="" 82="" currently="" known="" lobc="" snps="" were="" associated="" with="" eobc=""><0.05). low="" power="" is="" likely="" responsible="" for="" the="" remaining="" 50="" unassociated="" known="" lobc="" snps.="" the="" gene-based="" analysis="" identified="" an="" association="" between="" breast="" cancer="" and="" the="" phosphofructokinase-muscle="" (pfkm)="" gene="" on="" chromosome="" 12q13.11="" that="" met="" the="" genomewide="" gene-based="" threshold="" of="" 2.5x10-in="" conclusion,="" eobc="" and="" lobc="" appear="" to="" have="" similar="" genetic="" etiologies;="" the="" 5q11.2="" region="" may="" contain="" multiple="" distinct="" breast="" cancer="" loci;="" and="" the="" pfkm="" gene="" region="" is="" worthy="" of="" further="" investigation.="" these="" findings="" should="" enhance="" our="" understanding="" of="" the="" etiology="" of="" breast="">
