What You Are Giving Away With Those Home DNA Checks
“Even if you just send your Family Reconstruction DNA Test in Nigeria in for genealogical work, what these firms usually run is a SNP test a whole bunch of 1000’s of markers, though they may be solely looking for a few hundred markers,” Greely said. A SNP (pronounced “snip”) is a single nucleotide polymorphism, a single-letter difference within the genetic code which will cause illness or which will lead back to your nice-great grandfather.
The market may change over time, of course. As our understanding of genetics improves, issues like pharmacogenomics (the relationship between medication and genes) and nutrigenomics (the interplay between nutrition and genes) might develop into a lot bigger forces. What’s now thought-about “recreational” health testing could become more clinically related, and the genetic health market in general could show to be greater than that for ancestry and genealogy. However for now, as University College London researcher and genetic genealogist Debbie Kennett factors out, the biggest genomic dataset on the planet isn’t in the hands of governments, pharmaceutical firms or research organizations. “Instead,” she writes, “it is the ancestry companies which have been accumulating a lot of the genetic knowledge.”
