This multi-stage genome-wide association study in 11,705 BRCA1 mutation carriers identified three novel cancer risk-modifying loci: rs2290854 at 1q32 associated with breast cancer (HR=1.14), and rs17631303 (HR=1.27) and rs4691139 (HR=1.20) at 17q21.31 and 4q32.3 respectively associated with ovarian cancer. The 4q32.3 locus showed BRCA1-specific associations. These findings enable improved absolute risk estimation for BRCA1 carriers, with estimated breast cancer lifetime risks ranging from 28-50% for the lowest-risk 5% to 81-100% for the highest-risk 5%.
About MDM4
This gene encodes a nuclear protein that contains a p53 binding domain at the N-terminus and a RING finger domain at the C-terminus, and shows structural similarity to p53-binding protein MDM2. Both proteins bind the p53 tumor suppressor protein and inhibit its activity, and have been shown to be overexpressed in a variety of human cancers. However, unlike MDM2 which degrades p53, this protein inhibits p53 by binding its transcriptional activation domain. This protein also interacts with MDM2 protein via the RING finger domain, and inhibits the latter's degradation. So this protein can reverse MDM2-targeted degradation of p53, while maintaining suppression of p53 transactivation and apoptotic functions. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Feb 2011]
