DNA sequencing process

What are genes/DNA?

  • Genetic information is transmitted from one generation to the next in families by DNA.
  • The genetic information found in DNA tells our cells how to develop and what to do. 
  • Changes, or variations in our DNA, may or may not change the meaning of the instructions, and can change how cells function.

What is genome sequencing (or DNA testing)?

  • Genome sequencing reads our DNA “instructions” and enables us to identify changes or variations in these instructions that might underlie autism.
  • It involves taking a sample of blood or saliva, containing DNA. 
  • Being able to sequence or read this genetic information allows individuals and their whānau to better understand their health, wellbeing and differences. 
  • A great resource on genomic testing and considerations when taking part in genomic testing, can be found on the New South Wales Centre for Genetics Education.
