  St Jude has released some pretty amazing findings. Today is no different. The researchers there have implicated the BRCA 2 (the gene, not the mutations) in the development of the brain. The study found thatBRCA 2 triggers the repair of damaged DNA from cellular replication in nerve cells. This effect was also found to suppress the development of Medulloblastomas. These tumors account for 1/5 th of childhood brain tumors. When BRCA 2 function is impaired (as is the case in breast and ovarian cancers) the mice studied developed medulloblastomas. The Gene Sherpa Says: The jury's still out. It makes sense to me that this gene is involved in medulloblastoma. Especially because this gene is involved in Fanconi Anemia, which can present with brain abnormalities. However I caution the excitement...What prophylaxis is there for medulloblastoma? Brain- Ectomy(removal)? |
