Decoding your genes
I read an article in the latest Popular Mechanics magazine (Nov 2006) about Dr. Venter's decoding of his genetic make-up. My question is, will everybody be able to have their genetic make-up/blueprint analyzed in the future and what are the costs involved? This could be the key to what makes each individual tick along with discovering latent talents that were passed down from generation to generation. A must read for all into genetics. Expert, what is your take on this?

Dear Art

It is possible to have all your genes sequenced but it will be very expensive at this stage. For example just to have the two major genes for breast cancer screened for defects cost about R20 000 in the USA. In South Africa it costs about R2000 just to have 7 gene areas analysed in the same genes. And we have between 20000 and 400000 different genes. Discovering latent talents is already possible for things like althletic potential but those who are dedicated may still do better than those with the right genes so the complexity of gene-environment interaction required careful consideration before genetic screening is done.
