SVS, Population Genetics, and 1000 Genomes Phase 3

One frequent question I hear from SVS customers is whether whole exome sequence data can be used for principal components analysis (PCA) and other applications in population genetics. The answer is, “yes, but you need to be cautious.” What does … Continue reading

Genomic Prediction and How it’s Used

Golden Helix is excited to host a webinar on Tuesday August 26th discussing the Genomic Prediction methods which were recently integrated into the SVS software. Genomic prediction uses several pieces of information when calculating its results. Genetic information is used to predict … Continue reading

RefSeq Genes: Updated to NCBI Provided Alignments and Why You Care

You probably haven’t spent much time thinking about how we represent genes in a genomic reference sequence context. And by genes, I really mean transcripts since genes are just a collection of transcripts that produce the same product. But in … Continue reading

Population Structure + Genetic Background + Environment = Mixed Model

A few months ago, our CEO, Christophe Lambert, directed me toward an interesting commentary published in Nature Reviews Genetics by authors Bjarni J. Vilhjalmsson and Magnus Nordborg.  Population structure is frequently cited as a major source of confounding in GWAS, … Continue reading

What is Bioinformatic Filtering?

Recently I gave a presentation on bioinformatic filtering: the process of using quality scores, annotation databases, and functional prediction scores to intelligently and quickly reduce your variant search space. View the recording here» In this webcast, I mention that filtering … Continue reading

The What, Why, and How of Creating a Genome Map

Including the completion of the Human Genome Project in 2003, scientists have created whole genome sequence maps for over 1,000 species. From maize to oysters, the quest to investigate different species’ genetic code continues. Mapping is the “first step” that … Continue reading
