Detailed explanation-1: -DNA Sequencing Sequencing allows clinicians to determine if a gene or the region that regulates a gene (regulatory region of DNA) contains changes, or variants, linked to a disorder.

Detailed explanation-2: -Three major types of genetic testing are available in laboratories: cytogenetic (to examine whole chromosomes), biochemical (to measure protein produced by genes), and molecular (to look for small DNA mutations). (See Chapter 2 and Appendix I for more information.)

Detailed explanation-3: -Molecular diagnostic methods refer to the new genre of tests that detect abnormalities at the DNA level. Because genetic mutations are defined as heritable changes of an individual’s DNA, these tests represent the most direct approach in assessing whether a patient is carrying a particular mutation.

Detailed explanation-4: -What is molecular diagnostics? Molecular diagnostics, also called molecular pathology, involves taking DNA or RNA, the unique genetic code found in our cells, and analyzing the sequences for red flags that can pinpoint the potential emergence of a specific disease. The field has expanded rapidly in recent years.
