With the goal of understanding the genetic changes and mechanisms underlying human diseases, the Molecular Genomics Core (MGC) Facility supports NICHD investigators by providing next-generation deep sequencing and project data analysis.
Next-Generation sequencing and bioinformatics support
The MGC provides DNA and RNA sequencing services for genomic and genetic research to investigators within the NICHD. The MGC is currently operating with five sequencing machines. Most of our work is conducted on our two high-capacity, production-scale machines: an Illumina HiSeq 2500 and an Illumina NovaSeq 6000. To increase the throughput of the HiSeq 2500 even further, we have a cBot liquid handler for automated high-precision loading of sequencing chips. Two of the other sequencers, an Illumina MiSeq and an Ion Torrent Personal Genomics Machine, are smaller, faster machines, which can generate longer sequence reads of up to 400 base pairs. The fifth sequencer, is a Pacific Biosciences (PacBio) Sequel, which can sequence long single molecules of more than 100,000 base pairs. This array of sequencers provides a suite of scales and capabilities. Our sequencing services include whole-genome, whole-exome, targeted exome, and gene-specific DNA sequencing, as well as whole-transcriptome sequencing (RNA-Seq), microRNA sequencing, microbiome sequencing, bisulfite sequencing (DNA methylome), ChIP-Seq, and ribosomal profiling. The PacBio Sequel permits mutation phasing, structural variant analysis, transposon location identification, and other analyses that are not possible or practical with the other sequencers.
The MGC also operates a 10X Genomics Chromium Single Cell Controller. The Chromium converts a suspension of single cells or nuclei into cDNA libraries that are barcoded by cell or nucleus of origin. The cDNAs can then be converted into sequenceable libraries and run on our Illumina HiSeq 2500 or NovaSeq 6000 machines to generate thousands of cell-specific transcriptomes.
The MGC provides significant primary data-processing and downstream bioinformatic support and can assist in designing experiments or sequencing strategies (for example, optimization of targeted exome design). During the past year, the MGC provided sequencing for 245 projects (2,902 samples) across the full spectrum of sequencing types, generating 20,177 gigabases of sequence; the projects involved 37 NICHD Principal Investigators from 13 Affinity Groups. In addition to sequencing and providing our standard primary analysis of the resulting data, the MGC delivered enhanced bioinformatic support to 18 NICHD investigators across eight Affinity Groups. Our mission is to offer accurate and innovative sequencing and bioinformatic tools to facilitate research into the diagnosis, counseling, and treatment of hereditary disorders, and to support basic research that promotes understanding of human health and development.
