Lucky No. 14: ACMG adds new genes for reporting secondary findings

The American College of Medical Genetics and Genomics Secondary Findings Working Group has recently updated its recommendations.

Introducing NxClinical 6.0 — 5 key updates and improvements

The long-awaited NxClinical update is here! NxClinical 6.0 is packed with over 500 features and improvements - too many to talk about here but this blog features some of the highlights.

Publication notes superiority of NxClinical software for CNV detection from low pass sequencing

Low Pass Genome Sequencing (LP-GS) for detection of CNVs as a replacement to constitutional microarray analysis. The team evaluated a number of different tools and found NxClinical to have superiority in CNV detection and classification.

Promising results for a new non-invasive prenatal test that uses single circulating trophoblasts

A recent study from Arthur Beaudet’s lab at Baylor College of Medicine published in the American Journal of Human Genetics (AJHG) looks at the ability to detect fetal aneuploidies and copy number variants (CNVs) at 1Mb resolution from single circulating trophoblast (SCT) cells in maternal blood.

Recent publications illustrate the wide applicability of BioDiscovery’s CNV from NGS algorithm

The BAM MSR algorithm uses a set of “normal” samples to create a pooled reference to be used against the samples under analysis. Here are a few recent publications showing the algorithm’s versatility in handling different types of NGS data from panels to low-pass whole genome.

Significant Cost Savings with Single NGS Test vs. Other Strategies

At the American Society of Clinical Oncology (ASCO) meeting last month, Dr. Nathan Pennell, Director of the Lung Cancer Medical Oncology Program at the Cleveland Clinic, and his colleagues presented cost analysis in a model with different types of genetics testing in metastatic non-small cell lung cancer (mNSCLC). The team showed that upfront NGS leads to significant cost savings vs. sequential single-gene testing modalities.

Does reanalysis improve diagnostic yield?

A recent paper on the project shared results from a reanalysis in 2017 of the initial 1133 children using new knowledge and findings that have accumulated since the initial analysis. The pace at which improvements in genomic data technologies, analysis, and knowledge are moving, the group hypothesized that it is likely that diagnostic yield would increase via the reanalysis. They sought to determine how much of an improvement can be made over time.

Back from China with a Partnership with Be Creative

BioDiscovery inked a deal with Be Creative Lab (Beijing) Co. Ltd. where Be Creative will be the sole reseller and distributor of BioDiscovery products in China. Be Creative is a clinical genetic testing center in Beijing, China, providing diagnostic support for a number of hospitals. Be Creative debuted NxClinical 4.0 at the Clinical Applications Conference which focused on comprehensive application of SNP-Array, NGS and other technology platforms to enhance clinical diagnostics. The conference, hosted by Be Creative, brought together 200 clinical genetics experts.

Combined CNV and SNV detection from NGS panels in a clinical setting – a single test system is within reach!

Dr. Darine Villela and colleagues in Dr. Carla Rosenber's lab at the University of Sau Paulo, Brazil sought to find an integrated solution to combine two tests into one – one that was cost effective and easy to adopt in a clinical setting. They noted that there are several tools for CNV analysis from sequencing data, but the homemade tools are designed for a specific pipeline, are not user-friendly and require a high degree of bioinformatics expertise. They knew they needed a solution that would be easy to implement in a clinical lab and chose a commercial target enrichment kit and BioDiscovery’s Nexus Copy Number for analysis.

Introduction to NIPT and Liquid Biopsy

Two of the hottest fields in the genomic diagnostics market are NIPT (Noninvasive Prenatal Testing) and liquid biopsy. Both share the same mechanim by testing the circulating free DNA in the bloodstream, even though NIPT applies in the pregnancy diagnostics while Liquid Biopsy is for cancer.
