Genetic Fingerprinting for Human Diseases: Applications and Implications
DNA fingerprinting traditionally refers to the identification of individuals from blood and/or tissue samples for forensic purposes. But genetic fingerprinting can also include characterization of the genetic basis of human diseases, especially the inherited disorders. Some of the variants or haplotypes identified may run in families and thereby also have pathological or phenotypic connotations. The DNA sequencing technologies have evolved over the years, and nowadays, high-throughput techniques and applications are available with increased automation. Thus, genetic fingerprinting can have various connotations in relation to human diseases. The genetic testing done would depend on the clinical situation or phenotype, and what we are looking for in a specific patient or individual. Pretest and posttest counseling are important to facilitate decision-making.
