PATHOLOGY

Detailed explanation-1: -Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder.

Detailed explanation-2: -The DNA testing process is comprised of four main steps, including extraction, quantitation, amplification, and capillary electrophoresis.

Detailed explanation-3: -There are two different kinds of large-scale genetic tests. Exome sequencing looks at all the genes in the DNA (whole exome) or just the genes that are related to medical conditions (clinical exome). Genome sequencing is the largest genetic test and looks at all of a person’s DNA, not just the genes.

Detailed explanation-4: -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.
