Hi, at the risk of exposing my ignorance, a question: can someone point me to a reference that established the use of 30X coverage as a goal in sequencing? Where does this number come from? Why not 10X or 50X?

Usually related to the papers that used SNP arrays and NGS and tested the level of sequencing needed to call all heterozygote SNPs detected on the array by NGS or sanger sequencing. The first good example I remember is the Ventor diploid genome paper in Plos One but a number of similar examples are available. Scan the genome papers that also have a SNP array in the materials and methods and check their supplemental tables. But most I remember show diploid concordance >95% is not reached till around 26x or greater coverage

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...Today, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
