Ng N, Trudel M, Akslen LA: Germline BRCA mutations in addition to a basal BI-7273 web epithelial phenotype in breast cancer. J tl Cancer Inst, :.mainly aimed at identifying modifications within the coding sequences and in the donor cceptor splice web sites. Hence, mutations inside the promoter plus the untranslated regions, and significant rearrangements, are certainly not detected by these techniques. To assess the order EMA401 significance of BRCA and BRCA alterations which 
are neglected by standard screening procedures, we monitored germline rearrangements in these genes working with `multiplex ligationdependent probe amplification’ technology. A single hundred and seventynine Norwegian breast and ovarian cancer households were screened for rearrangements in BRCA whilst households have been tested for aberrations in BRCA. Whereas no 
rearrangements had been detected in BRCA, four distinct deletions have been discovered in BRCA. Those deletions origiting by Alumediated homologous recombition involve: exons, exons, exons and exon, respectively. The huge.kb deletion excluding exons in BRCA has been located each within the French and British breast cancer population. The deletions of exons, exons and exon have not been previously reported.
