Myriad is certified to offer genetic testing in every state in the United States.
This procedure doubles the number of bases that must be sequenced, but is a valuable step in detecting mutations. A deleterious or potentially deleterious mutation is subjected to reanalysis. Positive results are reported only when a mutation has been confirmed by repeating the analysis. This method is considered the gold standard of genetic testing, because it determines the identity and order of constituent bases in the protein-coding regions of both genes. This test involves direct gene sequencing of a small portion of the patient's DNA to determine if he or she carries a specific mutation.
