Wojcicki compares the recent pushback as the identical medical professionals felt back when the at-household pregnancy examination was produced.
To strike back again from critics of the FDA’s go to let 23andMe to promote the initially at-home genetic test for an inherited danger for cancer, Wojcicki wrote an op-ed in STAT. In the op-ed, Wojcicki compares the at-household genetic take a look at to the at-home being pregnant test that girls use to detect whether they may perhaps be expecting.
23andMe’s genetic exam analyzes DNA for 3 unique genetic variants on the BRCA1 and BRCA2 genes. These two genes are joined to an greater hazard of breast and ovarian cancers. These variants are primarily discovered in folks of Ashkenazi Jewish ancestry. Women of all ages who have just just one of the variants have a 45 p.c to 85 percent probability of building breast cancer by the age of 70.
Wojcicki defends the 23andMe genetic cancer check by stating that she believes people really should have a lot more direct entry to essential details. She cites the scientific tests that have concluded that as quite a few as 50 p.c of people today with one particular of the genetic mutations that could display symptoms of cancer wouldn’t qualify for a breast or ovarian cancer screening under recent recommendations.
Wojcicki likens the pushback from the genetic most cancers exam to the pushback by medical professionals when the home being pregnant examination was launched. Adding that medical practitioners assumed that if individuals realized the outcomes of a household pregnancy exam it would be too a great deal to bear.
23andMe’s genetic most cancers test has been criticized for portray an incomplete picture of the hazard of breast and ovarian most cancers. In a unique op-ed on STAT, Susan Domchek, a health care oncologist and affiliate professor of medicine, outlines the faults with 23andMe’s genetic take a look at.
Domchek highlighted the three key challenges with the 23andMe exams. The mutations which 23andMe assessments for are mainly found among people of Ashkenazi Jewish descent. Domchek claims that this makes the test unlikely to be helpful for people that usually are not of Ashkenazi descent. This results in a difficulty where by the man or woman may possibly nonetheless have a BRCA mutation even nevertheless the test suggests the individual will not have the mutations.
One more cause Domchek offers towards the at-household genetic cancer exam is that 23andMe’s examination searches for these kinds of a little number of cancer genes. Mutations in other genes can also maximize the chance of breast and ovarian cancers. Other genes also put men and women at risk for most cancers. Without having tests for those, it presents persons a wrong sense of security.
Domchek’s previous issue is that the 23andMe check does not take relatives historical past into account. Irrespective of the exam declaring a person can be adverse, their household heritage may well establish normally.
