Abstract
Genomic technologies are becoming a routine part of human genetic analysis. The exponential growth in DNA sequencing capability has brought an unprecedented understanding of human genetic variation and the identification of thousands of variants that impact human health. In this review, we describe the different types of DNA variation and provide an overview of existing DNA sequencing technologies and their applications. As genomic technologies and knowledge continue to advance, they will become integral in clinical practice. To accomplish the goal of personalized genomic medicine for patients, close collaborations between researchers and clinicians will be essential to develop and curate deep databases of genetic variation and their associated phenotypes.
