Using the AMP Guidelines for Rhabdoid Tumor Analysis in VSClinical

Jul 15, 2020

Introduction: Malignant Rhabdoid tumors (MRT) are among the most aggressive and lethal forms of infant and child cancer (1). These tumors are characterized by an unusual combination of mixed cellular elements similar to but not typical of teratomas and can originate at any anatomic location. When MRTs are present in…

Webcast on Big Data in Genomics

Sep 8, 2016

Wednesday, September 21st @ 12:00 pm EDT Every day, the trove of genomic data is growing. Clinics are sequencing targeted genes at high read depths to report out genetic tests. Research groups are adding new exomes and genomes to their disease-specific cohorts. Agricultural breeders are genotyping their herds and flocks…

Bridging Two Worlds: Lifting Over Your Variants to GRCh38

Jun 7, 2016

When the new human reference genome was released over two years ago, it was hailed as a significant step forward for next generation sequencing. Compared to GRCh37, the new GRCH38 reference assembly fixed gaps, repaired incorrect sequences and offered access to sections of the genome that had been previously unaccounted…

Scaling is in our DNA: Making Genomics Accessible

Feb 11, 2016

Scaling is in our DNA: Making Genomics Accessible One of the things I absolutely love about the work we do at Golden Helix is keeping up with the changes in data analysis driven by the iterative and generational leaps in technology. But one thing has always been a constant since…

The Clinical Genome Conference 2015 Highlights

Jun 30, 2015

This last week I had the pleasure of attending the fourth annual Clinical Genome Conference (TCGC) in Japantown, San Francisco and kicking off the conference by teaching a short course on Personal Genomics Variant Analysis and Interpretation. Some highlights of the conference from my perspective: Talking about clinical genomics is…

VarSeq: A bioinformatics Swiss Army knife

Dec 5, 2014

If you’ve seen the recent webinars given by Gabe Rudy and Bryce Christensen, you’ve no doubt been impressed by the capabilities of VarSeq when it comes to annotation and filtering. However, we sometimes forget that the power that enables all this complex analysis can also be used in more mundane…

Updates to ClinVar and dbSNPs: Fresh charts for Cromonaughts!

Aug 28, 2014

I’m sitting in the Smithsonian Air and Space Museum basking in the incredible product of human innovation and the hard work of countless engineers. My volunteer tour guide started us off at the Wright brother’s fliers and made a point of saying it was only 65 years from lift off at Kitty…

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

Aug 14, 2014

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 fact, there is more complexity here than you ever really…

The State of Variant Annotation: A Comparison of AnnoVar, snpEff and VEP

Jun 25, 2014

Up until a few weeks ago, I thought variant classification was basically a solved problem. I mean, how hard can it be? We look at variants all the time and say things like, “Well that one is probably not too detrimental since it’s a 3 base insertion, but this frameshift…

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…

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…

Guest Post: Next Generation Variant Calling

Sep 26, 2012

Editor’s Note by Gabe Rudy: I’ve had the chance to exchange thoughts, emails, and blog post comments for a while now with Jeff as he has written posts on NGS Leaders and engaged with me on 23andMe. He has also worked with Golden Helix software as part of Dr. Todd…

Have We Wasted 7 Years and $100 Million Dollars on GWAS Studies?

Jun 21, 2012

Type 2 Diabetes, Rheumatoid Arthritis, Obesity, Chrohn’s Diseases and Coronary Heart Disease are examples of common, chronic diseases that have a significant genetic component. It should be no surprise that these diseases have been the target of much genetic research. Yet over the past decade, the tools of our research…

Is Free Software Really Free?

May 23, 2012

The prevalence of open-source bioinformatic tools in the genetic research space is enormous. According to The North Shore LIJ Research Institute, there are over 500 genetic analysis software packages – the great majority of which are free – as of August 2010. Open-source tools are incredibly important in genetics. They…

Guest Post: Stepping Outside My Open-Source Comfort Zone: A First Look at Golden Helix SVS

May 16, 2012

I’m a huge supporter of the Free and Open Source Software movement. I’ve written more about R than anything else on my blog, all the code I post on my blog is free and open-source, and a while back I invited you to steal my blog under a cc-by-sa license. Every now and then,…
