In silico panels: An effective tool for performing targeted, outcome-driven analyses of WGS data

in silico panels

In our last post, we talked about the importance of periodically reanalyzing whole exome (WES) and whole genome sequencing (WGS) data for unsolved cases. An additional benefit of reanalysis of WGS data is that there’s no need to worry about coverage and changing pull-down kits as knowledge of exonic and regulatory regions of emerging importance grows. The full genomic sequence is already available. Which leads us to consider another related strength of WGS technology in this post: support for in silico panels.

Periodic data reanalysis leads to higher diagnostic yield

data reanalysis

A case came to us in early 2017. The patient was an adult male with symptoms of muscle weakness along with limb girdle and distal inclusion body myopathy, with a suspicion of autosomal dominant inheritance. We process new cases all the time, sequencing the whole genome to obtain the most comprehensive coverage of variants possible. And for the subset that don’t receive a diagnosis following interpretation, we routinely subject them to periodic reanalysis. But this particular case was a data reprocessing project from the very beginning …

Evolution of genomic care – part 3

clinical wgs

In the final installment of our three-part of the series, we’re looking at how the standard of care is continuing to evolve, as clinical whole genome sequence (WGS) testing enables a more comprehensive view of the exome while simultaneously identifying mitochondrial variants, structural aberrations and trinucleotide repeat expansions (including expansions of FMR1) with a single test …

Evolution of genomic care – part 2

wes

In this second installment of our three-part series, we’re looking at how whole exome sequence (WES) testing is increasingly being accepted as an alternative to targeted gene analysis, for faster and more cost-effective identification of causative SNVs and indels …

Evolution of genomic care – part 1

developmental delay

In a three-part series, we’re exploring how the standard of care, as it pertains to genetic testing, is evolving for rare disease diagnosis. In this first part we’re looking at the traditional approach to genetic testing by following the typical diagnostic journey of a young child with symptoms of developmental delay. Symptoms such as a delay in speech and language skills, social and emotional difficulties, and sensitivity to certain sensations …
