Baby To Be Born Without the Gene For Breast Cancer
manoftin writes to tell us that next week a baby will be born without the gene for breast cancer, according to the BBC. "But he said that, in this case, not carrying the BRCA1 gene would not guarantee any daughter born to the couple would be unaffected by breast cancer because there are other genetic and environmental causes. Dr Alan Thornhill, scientific director of the London Bridge Fertility, Gynaecology and Genetics Centre, said: 'While the technology and approach used in this case is fairly routine, it is the first time in the UK that a family has successfully eliminated a mutant breast cancer gene for their child. It is a victory for both the parents and the HFEA that licensed this treatment.'"
I don't understand what the real difference is from other types of embryo screening. Sure, there was a different method of screening here, but otherwise screening like this has been going on for a while. No new ethical implications that I see.
All that happened was screening. They didn't screw with nature, they just took a peek to see whether the embryo had the gene or not.
"licensed this treatment"?
That is without a doubt one of the scariest things I've read lately.
IIRC the ratio between women and men affected by breast cancer is 100:1. So it makes a big difference.
However, those statistics are about breast cancer in general. Maybe someone with a medical background can enlighten us about the specific ratio of BRCA1.
I don't read replies by ACs.
by knocking out BRCA that other, unintended consequences will result...
They are not knocking it out. They are selecting an embryo which has inherited the good (not known bad) copy of the BRCA gene.
