Abstract
Current genome-wide technologies allow interrogation and exploration of the human genome as never before. Next-generation sequencing (NGS) technologies, along with high resolution Single Nucleotide Polymorphisms (SNP) arrays and array Comparative Genomic Hybrization (aCGH) enable assessment of human genome variation at the finest resolution from base pair changes such as simple nucleotide variants (SNVs) to large copy-number variants (CNVs). The application of these genomic technologies in the clinical setting has also enabled the molecular characterization of genetic disorders and the understanding of the biological functions of more genes in human development, disease, and health. In this review, the current approaches and platforms available for high-throughput human genome analyses, the steps involved in these different methodologies from sample preparation to data analysis, their applications, and limitations are summarized and discussed.
