Fun in the Sun – Headed to Tri-Con and AGBT next week

Feb 5, 2014

Weather.com currently says it feels like -24 degrees outside (yes, that’s negative) here in Bozeman, Montana. Which is why I’m more than a little jealous of Gabe Rudy and Andreas Scherer who get to go to San Francisco and Marco Island next week, respectively, where the weather is little more……

Back to Basics: Importing/Exporting Data in Imputation Program Data Formats with SVS

Dec 31, 2013

In a recent blog post (Comparing BEAGLE, IMPUTE2, and Minimac Imputation Methods for Accuracy, Computation Time, and Memory Usage), Autumn Laughbaum compared three imputation programs. Data can be exported from, or imported into, SVS in the standard file formats for these and other imputation programs. The goal of this blog…

Comparing BEAGLE, IMPUTE2, and Minimac Imputation Methods for Accuracy, Computation Time, and Memory Usage

Jul 17, 2013

Genotype imputation is a common and useful practice that allows GWAS researchers to analyze untyped SNPs without the cost of genotyping millions of additional SNPs. In the Services Department at Golden Helix, we often perform imputation on client data, and we have our own software preferences for a variety of…

Vanessa Hayes, PhD and Desiree Petersen, PhD Use Population Genetics to Dig into Mankind’s Roots

Jun 26, 2013

Humans are said to have a 0.1% rate of diversity, seemingly small, but actually quite significant when considering the future of personalized medicine. Gaining a deeper understanding of this genetic variance can help determine susceptibility to disease as well as medicinal response and outcomes. One-third of human genetic diversity can…

Robert Kleta, MD, PhD and His Newly-Formed Team Publish in The New England Journal of Medicine in a Few Short Months with SVS

May 16, 2013

Thirteen years ago, Dr. Robert Kleta had never heard of a genome-wide association study (GWAS), let alone considered doing one. Now, Dr. Kleta and his colleagues at the University College of London regularly publish articles in The New England Journal of Medicine and other journals on the genetics of rare…

The Next Phase in Our Evolution

May 8, 2013

Time goes by fast. With the completion of the Human Genome Project in 2003, scientists worldwide were trying to understand the cause and effect of variations in the genome as they relate to functionalities, traits and disease. Along the way, we at Golden Helix helped researchers analyze data, discover variations…

The Murky Waters of Variant Nomenclature – You Could Be Missing Vital Information

May 6, 2013

When researchers realized they needed a way to report genetic variants in scientific literature using a consistent format, the Human Genome Variation Society (HGVS) mutation nomenclature was developed and quickly became the standard method for describing sequence variations. Increasingly, HGVS nomenclature is being used to describe variants in genetic variant…

The State of NGS Variant Calling: DON’T PANIC!!

Mar 25, 2013

I’m a believer in the signal. Whole genomes and exomes have lots of signal. Man, is it cool to look at a pile-up and see a mutation as clear as day that you arrived at after filtering through hundreds of thousands or even millions of candidates. When these signals sit…

Population Structure + Genetic Background + Environment = Mixed Model

Mar 22, 2013

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, but the authors of the article suggest that the problems…
