Genome-wide sequencing refers to two genetic tests, whole exome sequencing and whole genome sequencing, that allow health-care providers to look broadly at your child’s DNA.

Key points

  • Genome-wide sequencing can examine the entire genetic makeup of a person in a single test. It is used to identify potential genetic causes of your child’s medical condition.
  • Whole exome sequencing looks at the parts of a person’s DNA that provide instructions for making proteins.
  • Whole genome sequencing looks at all of a person’s DNA.
  • Genome-wide sequencing is increasingly used in clinical and research settings.
