Is testing your DNA really the answer?

I get asked about genetic testing all the time as I do carry out some gene testing in my line of work, to aid my clinical diagnoses.

The key point to understand here is that many genes may contribute to a particular disease, some of which are yet unknown.

The other variables at play are nutrition and environment that regulate the gene expression. This has a significant bearing on whether a condition is expressed, and this is where my study and work lies.

Testing your DNA should be interpreted by someone who has a balanced view on this.  The results also shouldn't go into the wrong hands.
