Can you create DNA in a lab?

With companies such as 23andMe mapping your genes, could someone take that raw data and artificially recreate your dna? 

What would be the implications of such a thing?

Yes, you can synthesize DNA in the lab.
But mostly it's shorter stretches, from 10s to 100s of basepairs. They are widely used in molecular biology and genetics labs.
If you want to generate a whole genome from scratch that's a bit more complicated. Genomes can be very large and repetitive which can make quality control more tedious.
