I've just seen an advert on TV for a company offering DNA reports so I looked online to see what it was about. For £125 they will send you a saliva swab which you return and they test your DNA for markers. Most of the things they tell you are the harmless and blatantly obvious such as you are likely to have brown eyes. Doh I know that from looking in the mirror.
But they also tell you if you have genetic risk factors such as, what they call, the Alzheimer's variant. If you have this apparently you have a higher risk of developing the condition. They don't tell you what gene is affected even though several genes can be involved plus many unknown factors. They suggest that you contact your health provider for advice. Jeez GPs are going to love this.
What's the point of this other that to get money out of people?
