Accurate Annotations: Updates to the NHLBI Exome Sequencing Project Variant Catalog

         May 19, 2015

Since its early release in early 2012, the population frequencies from the GO Exome Sequencing Project (ESP) – from the National Heart, Lung and Blood Institute (NHLBI) have been a staple of the genomic community. With the recent release of ExAC exome variant frequencies, the ESP has been surpassed as the largest cohort of publicly available variant frequencies (by nearly… Read more »

Unique Labs, Common Tool: Making VarSeq Ready for Clinical Workflows

         April 9, 2015

As VarSeq has been evaluated and chosen by more and more clinical labs, I have come to respect how unique each lab’s analytical use cases are. Different labs may specialize in cancer therapy management, specific hereditary disorders, focused gene panels or whole exomes. Some may expect to spend just minutes validating the analytics and the presence or absence of well-characterized… Read more »

Supercentenarian Variant Annotation: Complex to Primitive

         March 19, 2015

In a previous blog post, I demonstrated using VarSeq to directly analyze the whole genomes of 17 supercentenarians. Since then, I have been working with the variant set from these long-lived genomes to prepare a public data track useful for annotation and filtering. Well, we just published the track last week, and I’m excited to share some of the details… Read more »

What TriCon 2015 Foreshadows for Clinical Genomics

         February 25, 2015

I spent a very eventful week at the Molecular TriCon in downtown San Francisco, and have been pondering the very clear trends that emerged by attending the clinical and NGS focused talks. Cancer gene panels make sense economically and as “massively parallel” tests to inform therapy, but they are bound to get more complex. Liquid biopsies of circulating tumor DNA… Read more »

In Pursuit of Longevity: Analyzing the Supercentenarian Whole Genomes with VarSeq

         January 13, 2015

If you haven’t been closely watching the twittersphere or other headline sources of the genetics community, you may have missed the recent chatter about the whole genome sequencing of 17 supercentenarians (people who live beyond 110 years). While genetics only explains 20-30% of the longevity of those with average life-spans, it turns out there is a number of good reasons… Read more »

6 Population Catalogs Compared with the ExAC 61,486 Exomes

         November 13, 2014

To say the announcement of Dan MacArthur’s group’s release of the Exome Aggregation Consortium (ExAC) data was highly anticipated at ASHG 2014 would be an understatement. Basically, there were two types of talks at ASHG. Those that proceeded the official ExAC release talk and referred to it, and those that followed the talk and referred to it. Why is this… Read more »

VarSeq: Making Variant Discovery and Gene Panels Easy

         September 29, 2014

Last week, our CEO Andreas Scherer announced our entrance into the clinical testing market with VarSeq. This week, I will be giving a webcast on Wednesday introducing this new tool and demonstrating its capabilities. (Register for the webcast) VarSeq’s focused purpose is making NGS gene testing and variant discovery efficient, scalable and accessible to users with a broad range of backgrounds and specialties. In this blog post, we will examine the use cases that VarSeq supports in more detail,… Read more »

Updates to ClinVar and dbSNPs: Fresh charts for Cromonaughts!

         August 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 Hawk to the landing of a man on the moon…. Read more »

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

         August 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 wanted to know about. Andrew Jesaitis covered some of this… Read more »

The New Human Genome Reference and Clinical Grade Annotations: It’s All About the Coordinates

         February 17, 2014

On my flight back from this year’s Molecular Tri-Conference in San Francisco, I couldn’t help but ruminate over the intriguing talks, engaging round table discussions, and fabulous dinners with fellow speakers. And I kept returning to the topic of how we aggregate, share, and update data in the interest of understanding our genomes. Of course, there were many examples of… Read more »

All I Want for Christmas Is a New File Format for Genomics

         December 16, 2013

Tis the season of quiet, productive hours. I’ve been spending a lot of mine thinking about file formats. Actually, I’ve been spending mine implementing a new one, but more on that later. File formats are amazingly important in big data science. In genomics, it is hard not to be awed by how successful the BAM file format is. I thought… Read more »

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 databases as well. There are some practical issues that researchers… Read more »

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

         March 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 right in the genomic “sweet spot” of mappable regions with… Read more »

What Can Exomes Tell Us About the Pathology of Complex Disorders?

         February 26, 2013

My investigation into my wife’s rare autoimmune disease I recently got invited to speak at the plenary session of AGBT about my experience in receiving and interpreting my Direct to Consumer (DTC) exomes. I’ve touched on this before in my post discussing my own exome and a caution for clinical labs setting up a GATK pipeline based on buggy variants… Read more »

GATK is a Research Tool. Clinics Beware.

         December 3, 2012

In preparation for a webcast I’ll be giving on Wednesday on my own exome, I’ve been spending more time with variant callers and the myriad of false-positives one has to wade through to get to interesting, or potentially significant, variants. So recently, I was happy to see a message in my inbox from the 23andMe exome team saying they had… Read more »

         November 28, 2012

Join me on December 5th for a one-hour webcast as I explore my personal exome provided by the Exome Pilot project of 23andMe. Exome sequencing has seen many success stories in the realm of diagnosing highly penetrant monogenic disorders as well as in informing treatment of certain cancers. As the use of exome sequencing expands to more complex polygenic disorders… Read more »

To Find a Killer Variant: Successes and Challenges on the Journey to Mass Adoption of NGS in the Clinic

         October 22, 2012

Recently, I have been spending some time analyzing real patient data. I’m preparing for a webcast I’ll be giving in which I will walk through the process of replicating the findings of Dr. Gholson Lyon‘s study on the novel disease diagnosis he named Ogden Syndrome. Being so close to data that comes directly from clinical settings got me thinking about… Read more »

One Track to Rule Them All: Close but not quite from the 1000 Genomes Project

         July 31, 2012

I recently curated the latest population frequency catalog from the 1000 Genomes Project onto our annotation servers, and I had very high hopes for this track. First of all, I applaud 1000 Genomes for the amount of effort they have put in to providing the community with the largest set of high-quality whole genome controls available. My high hopes are… Read more »
