To evaluate the potential contribution of mutations in the BRCA1 and BRCA2 genes to male breast cancer (MBC), we expanded a previous study to screen a total of 261 Israeli men diagnosed with breast carcinoma. A total of 21 BRCA2 6174delT and 8 BRCA1 185delAG mutations were found. Similar frequencies of BRCA1 and BRCA2 mutation carriers were found among Ashkenazi (12.8%) and non-Ashkenazi Jews (9.1%). The combined prevalence of BRCA1/BRCA2 founder mutations among Ashkenazi Jewish men is slightly higher than for women, due to a higher frequency of BRCA2 mutations.
为评估BRCA1和BRCA2基因突变对男性乳腺癌(MBC)的潜在影响,我们扩展了之前的一项研究,对总共261名被诊断患有乳腺癌的以色列男性进行了筛查。共发现21例BRCA2 6174delT突变和8例BRCA1 185delAG突变。在阿什肯纳兹犹太人(12.8%)和非阿什肯纳兹犹太人(9.1%)中发现BRCA1和BRCA2突变携带者的频率相似。由于BRCA2突变频率较高,阿什肯纳兹犹太男性中BRCA1/BRCA2始祖突变的综合患病率略高于女性。
