Understanding the Contrast: SNP vs. Mutation

While the terms SNP and mutation are sometimes used interchangeably, they describe different types of DNA changes. Understanding the difference helps you interpret genetic results more accurately.

What is a Mutation?

A mutation is a change in DNA that is relatively rare and can significantly affect how a gene functions. These changes typically occur in less than 1% of the population and are more likely to be associated with genetic disorders or notable health effects.

What is a SNP?

SNP stands for Single Nucleotide Polymorphism (pronounced "snip"). It's a specific type of DNA variation involving a change in a single building block of DNA. SNPs are common—found in more than 1% of the population—and usually have small or neutral effects on health, though some can influence traits or health risks in subtle ways.

Key Differences at a Glance

• Mutations: Rare DNA changes that often have larger effects
• SNPs: Common variations that usually have minor or gradual impacts

Why This Matters for You

SelfDecode focuses on SNPs because these common variations help explain differences in health, traits, and responses between individuals. Rather than looking for rare disease-causing mutations, we analyze the genetic variations that contribute to your unique health profile and provide personalized insights based on your genetic makeup.
