Abstract

The advancement of DNA sequencing technologies has revolutionized the way we approach disease detection and diagnosis. Through the identification of genetic markers, specific DNA sequences associated with particular diseases or predispositions, clinicians can now more accurately predict, diagnose, and even prevent various health conditions. Genetic markers, including single nucleotide polymorphisms (SNPs), gene mutations, and epigenetic modifications, offer valuable insights into an individual's genetic makeup, enabling personalized treatment strategies. This paper explores the role of genetic markers in disease detection, the use of DNA sequencing to identify these markers, and the implications for precision medicine. With the ongoing development of sequencing technologies, the potential to improve early diagnosis, enhance treatment efficacy, and reduce disease burden is increasingly becoming a reality, paving the way for more individualized healthcare approaches.
