During the first 6 years of the Program of Genetic Counselling in Cancer of Valencia (eastern Spain), 310 mutations (155 in BRCA1 and 155 in BRCA2) in 1,763 hereditary breast (BC) and ovarian cancer (OC) families were identified. Of the mutations found 105 were distinct (53 in BRCA1 and 52 in BRCA2), eight new and 37 recurrent. Two of the novel mutations(More)
This study aims to identify signatures of miR associated with hereditary, BRCA1 or BRCA2 mutation positive breast cancer (BC), and non-hereditary BC, either sporadic (SBC) or non-informative (BRCAX). Moreover, we search for signatures associated with tumor stage, immunohistochemistry and tumor molecular profile. Twenty formalin fixed paraffin embedded(More)
The study aims to identify the relevance of immunohistochemistry (IHC), copy number aberrations (CNA) and epigenetic disorders in BRCAness breast cancers (BCs). We studied 95 paraffin included BCs, of which 41 carried BRCA1/BRCA2 germline mutations and 54 were non hereditary (BRCAX/Sporadic). Samples were assessed for BRCA1ness and CNAs by Multiplex(More)
The true prevalence of BRCA1/BRCA2 (BRCAs) germline mutations in sporadic breast or ovarian cancer (SBC/SOC) in Caucasian population is not well established. The aim of the study is to establish the prevalence of BRCAs mutations in SBC to ponder its relevance in the programs of genetic counseling in cancer and to explore the genotype-phenotype relationship(More)
