Basic question

What is a SNP, and why would I care?

A SNP is a common single-letter difference in the genome. One SNP does not define your life, but many SNPs together can help explain medication response, risk, and metabolism.

What matters most

  • Fern Gene is not about overdramatizing one marker.
  • The point is to organize many evidence-backed differences into usable results.
  • What matters is not the term itself, but what those differences mean for you.
