We examined associations between common germline genetic variation in 13 genes involved in cell cycle control (CCND1, CCND2, CCND3, CCNE1, CDK2 [p33], CDK4, CDK6, CDKN1A [p21, Cip1], CDKN1B [p27, Kip1], CDKN2A [p16], CDKN2B [p15], CDKN2C [p18], and CDKN2D [p19]) and survival among women diagnosed with invasive breast cancer participating in the SEARCH (Studies of Epidemiology and Risk factors in Cancer Heredity) breast cancer study.
In situ hybridization of the 52K-9 cDNA probe on normal lymphocytes assigned the 52K cathepsin D gene at the extremity of the short arm of chromosome 11, in the p15 band, close to the H-ras gene and in the region whose deletion increases the risk of invasive breast cancer.
