If you think of a gene as a page in a book, “gene sequencing” refers to reading across each letter of that page to see if there are any “spelling mistakes” in the genetic code. Gene sequencing would detect if “cat” in the book is misspelled as “ctt”. Some coding changes are normal and make us unique individuals. Other coding differences can result in disease.
