About this study
The purpose of this research use only (RUO) study is to detect genomic structural variants (SVs) in human DNA by Optical Genome Mapping (OGM) using the Bionano Genomics Saphyr system. SVs are a type of genetic alternation that includes deletions, duplications, and both balanced and unbalanced rearrangements (ex: inversions or translocations), as well as specific repeat expansions and contractions. The results of OGM analysis will be compared to prior clinical genetic test results to determine how OGM compares to current standard of care (SOC) clinical test methods such as chromosomal microarray analysis (CMA), karyotyping, Southern blot analysis, polymerase chain reaction (PCR), fluorescence in situ hybridization (FISH), and/or next generation sequencing (NGS), etc.
Read the detailed description
Optical genome mapping (OGM) is an emerging next-generation cytogenomic tool that enables a comprehensive analysis of structural variants (SVs) in the genome. OGM, in its current iteration, is performed on the Saphyr system, which is developed and marketed by Bionano Genomics (San Diego, CA). OGM employs imaging of ultra-long DNA molecules (>150 kbp) that are labeled at a unique 6 base-pair sequence motif (CTTAAG) that occurs throughout the genome. The images of the labeled DNA molecules are used to generate a de novo assembly that can be compared to a reference genome to identify all classes of SVs, such as deletions, duplications, balanced/ unbalanced genomic rearrangements (insertions, inversions, and translocations), and repeat array expansions/contractions). In addition, a separate coverage-based algorithm enables the detection of genome-wide copy number analysis (similar to CMA), and the absence of heterozygosity (AOH) analysis. In the same assay, a concurrent or stepwise data analysis pipeline allows for sizing pathogenic CGG repeat expansions (consistent with fragile X syndrome) as well as D4Z4 repeat contractions which are consistent with facioscapulohumeral muscular dystrophy type 1 (FSHD1). Recently, in several studies, OGM has demonstrated excellent concordance with standard-of-care testing. Importantly, the OGM workflow can provide results within three-five days.
The aim of this double-blinded, multi-site, retrospective, observational, Institutional Review Board (IRB)-approved study is to evaluate the concordance of structural variant detection by OGM compared to standard of care tests (such as CMA, karyotyping, Southern blot analysis, PCR, FISH, and/or NGS, etc.), in a large cohort containing a variety of SVs including aneuploidies, intragenic and contiguous deletions, duplications, balanced and unbalanced translocations, inversions, isochromosomes, ring chromosomes, repeat expansions, repeat contractions, and more. This study is also designed to assess the sensitivity, specificity, and reproducibility of OGM analysis conducted at multiple sites, by numerous operators, and on different Saphyr instruments. Consensus testing and interpretation protocols were developed and implemented at all sites.

Questions about this trial
What is this clinical trial studying?
An observational study of Developmental Disability and Intellectual Disability, run by Bionano Genomics at 8 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 7 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Alex Hastie, PhD (267-315-0914, ahastie@bionanogenomics.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sensitivity/Concordance and specificity of OGM with standard of care testing for detection of structural variants. (time frame: Through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05295277, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
