NGS BIOINFORMATICS SOMATIC VALIDATED MATERIAL - NGSBV
Analytes/procedures in bold type are regulated for proficiency testing by the Centers for Medicare & Medicaid Services (CMS).
Challenges per Shipment
Number of Activities
Somatic in silico mutagenized sequencing file
Two online activities per year
Additional Information/Minimum Requirements
This in silico program is designed to optimize bioinformatics pipelines, augment validations, and assist with pipeline verification after changes to NGS/ bioinformatics processes. This is not traditional proficiency testing and no results will be returned to the CAP; information regarding the variants introduced will be sent along with the mutagenized file.
Laboratories must provide a gene panel or exome sequencing data file (FASTQ or unaligned BAM) that has been generated using their current clinical sequencing protocols from one of the following sources: a specimen from the NGS-Germline program or from one of the following NIST Reference Material cell lines: RM 8398 (NA12878), RM 8391, RM 8392, or RM 8393. Specimens from the NGSST and NGSHM programs or additional Coriell/NIST Reference Material cell lines cannot be used for this program.
FASTQs or unaligned BAMs must be submitted along with a BED file describing the regions targeted and interrogated by your laboratory.
The mutagenized sequencing file will contain up to 75 somatic variants (depending on the size of the panel/exome provided) at allele fractions from 3% to 99% (higher allele fraction to mimic loss of heterozygosity or homozygosity) and will include:
Microsatellite instability at mono nucleotide tracts included in the submitted capture design
Simulated artifactual sequence
All variants will be modeled based on actual somatic mutations from the COSMIC and/or cBIOPORTAL databases
Laboratories can transfer and download files from most modern browsers/ operating systems. For the most up-to-date information on system requirements, go to cap.org and click System Requirements, located at the bottom of the home page.
Due to the extremely large file sizes, a minimum allowable transfer speed of 40 Mbps or higher is needed to ensure successful transfer of your laboratory’s sequencing files to the CAP. Contact your IT department for allowable transfer speeds to determine estimated transfer time and browser/operating system access.
Laboratories must comply with all of the above requirements to participate in this program. Additional information and steps to provide your laboratory’s sequencing file will be included in the kit materials.
One panel or exome sequencing data file, originating from your laboratory and provided to the CAP, for in silico mutagenesis
The mutagenized panel or exome sequencing data file is to be downloaded and analyzed by your laboratory bioinformatics pipeline and compared with the variant information provided by CAP
Your CAP shipping contact will be notified via email when the activity is available
