Gene sequencing |
process of isolating a single gene from a person's DNA, then decoding the sequence of nucleotides. The process is relatively expensive ($1,000 or more). Sometimes the entire gene is decoded and sometimes only the extrons (the most important parts) are decoded. Different people can have slightly different sequences (variants) with little or no impact on how well the gene works. However, some errors in a gene's sequence can have serious consequences. |
