History

The need for a centralized core facility for human genome research at SickKids Hospital prompted the establishment of The Centre for Applied Genomics (TCAG) in 1998.[ citation needed ] The founding director and associate director were Drs. Lap-Chee Tsui and Stephen W. Scherer, respectively. Scherer is now the scientific director.

Funding from the Canada Foundation for Innovation (CFI) enabled TCAG to form by consolidating existing core facilities including the Medical Research Council of Canada Genome Resource Facility, the Canadian Genetic Diseases Network (CGDN) large insert clone core, the CGDN DNA Sequencing Core and the SickKids Biotechnology Service DNA Sequencing and Synthesis labs. A genome-wide microsatellite genotyping laboratory at the Ottawa Health Research Institute, led by Dennis Bulman, was added. Subsequently, operational funding from the CIHR Genomics Special Projects panel provided for additional staff.

In 2001, a proposal entitled "Genome Resource Core Platform" was submitted to the then newly formed Genome Canada. This provided operational support, enhancing existing facilities and adding a mouse genotyping core at the University of Toronto led by Lucy Osborne.[ citation needed ] In 2002, SickKids built a new Affymetrix microarray facility. This core has quickly grown to become the largest such service centre in Canada and is in the top ten in North America. [2]

In 2004, TCAG entered a second phase of development driven by a $12 million CFI/Ontario Innovation Trust funded project entitled "Integrative Genomics for Health Research", [3] allowing for consolidation of the mouse genotyping core with the SickKids facilities. This award also supported the establishment of an "Ontario Population Genomics Repository" (OPGP) to be used as controls in studies of common diseases. To efficiently complete this project, TCAG partnered with John McLaughlin's group at Mount Sinai Hospital (Toronto).

In May, 2004, an application to the newly announced CFI Research Hospital Fund resulted in a $10.9 million award to build out lab space and consolidate all operations on the 14th and 15th floors of the Toronto Medical Discovery Tower (TMDT) in the MaRS Discovery District. TCAG was the first occupant of TMDT (in August, 2005), quickly followed by other SickKids scientists. Investments in computer infrastructure from the 2003 CFI/Ontario Innovation Trust competition resulted in the establishment of new phases of the high-performance computing cluster (HPF) that is currently used by TCAG and many other users, to allow analysis of large genomic datasets arising from new microarray and sequencing technologies. Further enhancements to the TCAG infrastructure were supported by a $10.7 million renewal grant from CFI's Leading Edge Fund competition, entitled "Integrative Genomics for Health Research – Phase II", awarded in June 2009. [4] More recently, a CFI grant entitled "The Centre for Applied Genomics: Paediatric Genomes to Outcomes" provided further infrastructure support. [5] In October 2013, TCAG moved to the Peter Gilgan Centre for Research and Learning, a new building housing the SickKids Research Institute. [6]

TCAG operates in large part on Science and Technology Innovation Centre (STIC) funds from Genome Canada, administered by the Ontario Genomics Institute.

Research

Current research at TCAG centres around large-scale projects performed by facility personnel, including support of Genome Canada projects, and a significant focus on the genetics of autism spectrum disorders and structural variation of the human genome. Service work is also performed for over 600 other academic, private sector and government labs each year, drawn from 30 different countries and spanning a wide variety of research disciplines. [7]

Past research at TCAG is reflected by numerous peer-reviewed scientific publications. In 2008, TCAG Scientific Directors, Associate Scientists and staff co-authored 58 peer-reviewed manuscripts dependent in some way (either entirely, or in part) on the platform infrastructure, as documented in PubMed. [8] Since 2002, over 270 such papers have been published. [9] Support of other researchers worldwide is found in many similar publications, with at least 145 papers in scholarly journals, book chapters, or graduate thesis dissertations acknowledging support or use of database resources during 2008 alone. [10]

Historical papers include:

TCAG was also integral to publications describing the decoding of human chromosome 7, [18] the discovery of large-scale copy number variation in the human genome, [19] [20] and the analysis of the first diploid human genome sequence (with the J. Craig Venter Institute). [21]

Genome Canada projects

As a Science and Technology Innovation Centre of Genome Canada, TCAG currently supports numerous large-scale projects, including research on autism spectrum disorders, structural variation of the human genome, integrative biology, conditional mouse mutagenesis, interactions of signaling molecules, type I diabetes, cancer stem cells, Cystic Fibrosis, biodiversity, structural biology, and stem cells, from Genome Canada's Competition III, New Technology Development and Applied Genomics Research in Bioproducts or Crops (ABC) competitions. [22] [23] [24] The centre is now working with applicants in the Large-Scale Applied Research Project [25] and Advancing Technology Innovation Through Discovery [26] competitions.

Databases

TCAG also hosts and curates websites and databases developed from supported projects, namely The Chromosome 7 Database, The Database of Genomic Variants, [27] the Segmental Duplication Database, the Autism Chromosome Rearrangement Database, and others. [28] These databases contain publicly available information.

Core facilities

TCAG DNA Synthesis Facility TCAG lab.jpg
TCAG DNA Synthesis Facility

TCAG employs a variety of genomic technologies to support different types of experimentation. These are organized into separate Core Facilities, with dedicated managers.

Informatics and biostatistics

The Bioinformatics team assists with data handling and analysis, and develops new algorithms and analytical methods, with a focus on the analysis of high-throughput ("next-generation") sequencing data. The Statistical Analysis group provides project consultation and power analysis, statistical analysis (genetic, microarray, and pathway data, epidemiology, population genetics), and copy number variation analysis, as well as developing new statistical methods.

DNA sequencing and synthesis

The facility uses conventional capillary Sanger sequencing on Applied Biosystems 3730xl instruments, governed by a Laboratory Information Management System (LIMS). Additionally, next-generation sequencing (NGS) using Illumina HiSeq 2500 and HiScan SQ instruments, Life Technologies Ion Proton and Applied Biosystems SOLiD instruments, and a 454/Roche GS-FLX Titanium instrument is performed. A key component of this facility is the use of high-performance computing and bioinformatics support for NGS analysis.

The Oligonucleotide Synthesis component of this facility makes conventional, long (up to 120 bases) and modified oligonucleotides, and purifies these by desalting, cartridge or high-performance liquid chromatography (HPLC).

Microarray and genetic analysis

The Microarray and Gene Expression Core Facility has a dedicated manager, and operates technologies from Affymetrix, Agilent and Illumina. Additionally, there is a wide variety of analytical software packages available for on-site data analysis.

Cytogenomics and genome resources

The Cytogenomics and Genome Resources Core Facility has a single manager between these two functions. Cytogenomics includes karyotyping and spectral (SKY) karyotyping (for mouse, human, and other species), fluorescent in situ hybridization (FISH) mapping, transgenic insertion site mapping (G-to-FISH mapping) and clone labeling for FISH experiments. The Genome Resources components includes a clone repository (Mammalian Gene Collection (MGC) cDNA (mouse and human), genomic clones including human bacterial artificial chromosomes (BACs)) and provides project consultation and design assistance (annotation, database queries, probe selection). It also provides cDNA library screening and quantitative PCR.

Genetic analysis

The Genetic Analysis area includes capillary-based genotyping (Applied Biosystems TaqMan and SNaPshot, microsatellites), custom genotyping (e.g. heteroduplex analysis), mouse genotyping (for cross progeny and genetic linkage analysis), and methylation analysis (for epigenetics research).

Biobanking

The Biobanking Core Facility has its own dedicated manager. It performs white cell immortalization (from blood) and banking, fibroblast culture and banking, culture and banking of other cell types including non-human cells, genomic DNA preparation from blood, saliva, tissues or cells, and whole-genome amplification (WGA).

Funding sources

TCAG is funded by several agencies, including the Canada Foundation for Innovation (CFI), Genome Canada through the Ontario Genomics Institute, the Ontario Ministry of Research and Innovation. Additionally, philanthropic donations are administered by The Hospital for Sick Children Foundation, and specific research projects are funded by a wide variety of agencies and charitable foundations.

<span class="mw-page-title-main">Genomics</span> Discipline in genetics

Genomics is an interdisciplinary field of biology focusing on the structure, function, evolution, mapping, and editing of genomes. A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration. In contrast to genetics, which refers to the study of individual genes and their roles in inheritance, genomics aims at the collective characterization and quantification of all of an organism's genes, their interrelations and influence on the organism. Genes may direct the production of proteins with the assistance of enzymes and messenger molecules. In turn, proteins make up body structures such as organs and tissues as well as control chemical reactions and carry signals between cells. Genomics also involves the sequencing and analysis of genomes through uses of high throughput DNA sequencing and bioinformatics to assemble and analyze the function and structure of entire genomes. Advances in genomics have triggered a revolution in discovery-based research and systems biology to facilitate understanding of even the most complex biological systems such as the brain.

The Human Genome Project (HGP) was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying, mapping and sequencing all of the genes of the human genome from both a physical and a functional standpoint. It started in 1990 and was completed in 2003. It remains the world's largest collaborative biological project. Planning for the project started after it was adopted in 1984 by the US government, and it officially launched in 1990. It was declared complete on April 14, 2003, and included about 92% of the genome. Level "complete genome" was achieved in May 2021, with a remaining only 0.3% bases covered by potential issues. The final gapless assembly was finished in January 2022.

Thomas James Hudson, O.C., is a Canadian genome scientist noted for his leading role in the generation of physical maps of the human and mouse genomes and also his role in the International HapMap Project whose goal is to develop a haplotype map of the human genome.

Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips, or partial or full genome sequencing. Once the genotypes are known, the individual's variations can be compared with the published literature to determine likelihood of trait expression, ancestry inference and disease risk.

Expenditures by Canadian universities on scientific research and development accounted for about 40% of all spending on scientific research and development in Canada in 2006.

The 1000 Genomes Project, launched in January 2008, was an international research effort to establish by far the most detailed catalogue of human genetic variation. Scientists planned to sequence the genomes of at least one thousand anonymous participants from a number of different ethnic groups within the following three years, using newly developed technologies which were faster and less expensive. In 2010, the project finished its pilot phase, which was described in detail in a publication in the journal Nature. In 2012, the sequencing of 1092 genomes was announced in a Nature publication. In 2015, two papers in Nature reported results and the completion of the project and opportunities for future research.

<span class="mw-page-title-main">Whole genome sequencing</span> Determining nearly the entirety of the DNA sequence of an organisms genome at a single time

Whole genome sequencing (WGS), also known as full genome sequencing, complete genome sequencing, or entire genome sequencing, is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondria and, for plants, in the chloroplast.

Exome sequencing, also known as whole exome sequencing (WES), is a genomic technique for sequencing all of the protein-coding regions of genes in a genome. It consists of two steps: the first step is to select only the subset of DNA that encodes proteins. These regions are known as exons—humans have about 180,000 exons, constituting about 1% of the human genome, or approximately 30 million base pairs. The second step is to sequence the exonic DNA using any high-throughput DNA sequencing technology.
