First Extensive Validation Study of Saphyr for Constitutional Genetic Disorders by European Consortium Shows 100% Concordance to Standard Cytogenetics and Describes Resolution of Cases of Long-Standing, Undiagnosed Disease

First large study in constitutional genetic diseases showed 100% concordance to gold-standard cytogenetic testingIn patients with leukemia, Saphyr enabled crucial discoveries including novel fusion events never described before in that diseaseSaphyr solved previously unidentified genetic diseases by finding novel mutationsMaking continued progress on goal to become the new standard of digital cytogenetic testingSAN DIEGO, July 08, 2020 (GLOBE NEWSWIRE) — Bionano Genomics, Inc. (Nasdaq: BNGO) announced today that two top cytogeneticists from leading institutions in The Netherlands and France presented their research data as part of a multicentric, international effort to compare data generated with Bionano’s Saphyr system against gold standard cytogenetic methods consisting of karyotyping, FISH, and/or chromosomal microarray in patients with a variety of constitutional or inherited genetic disorders and in patients with leukemias. In back-to-back online presentations, each showed 100% concordance between Saphyr and standard cytogenetics along with other discoveries that extend the capabilities of the current standard of care.Summary of data presentations:In a webinar originally hosted by LabRoots on Friday, June 22, Dr. Laila El Khattabi from the Cochin Hospital in Paris, France discussed how Saphyr improved structural variant detection for constitutional chromosomal aberrations in her research. The data originate from an international multi-center effort between the hospitals of Paris-Cochin, Lyon and Clermont-Ferrand and the Radboud University Medical Center in the Netherlands, as part of the first international consortium to validate Saphyr for constitutional cytogenetic analysis. The consortium compared the performance of Saphyr against the combination of karyotyping, FISH and array-based methods in 85 samples with a variety of constitutional aberrations including deletions, duplications, balanced and unbalanced translocations, inversions, ring chromosomes and aneuploidies in patients with intellectual disabilities and recurrent miscarriages. Saphyr showed 100% concordance with gold standard methods in these 85 samples. Dr. El Khattabi expressed the consortium’s confidence in Saphyr’s potential to largely replace standard cytogenetic testing methods in the future. A manuscript describing the study results will be submitted for publication in the coming weeks.Dr. Alexander Hoischen from Radboud University Medical Center described how Bionano genome imaging identified likely pathogenic variants in 25% of unsolved rare disease cases analyzed with Saphyr. Dr. Hoischen presented two of these research cases, which involved families with undiagnosed genetic disorders. The first case involved a rare and aggressive childhood tumor named Atypical Teratoid Rhabdoid Tumor (ATRT) in which Saphyr detected an insertion in the SMARCB1 gene in a family affected by ATRT, while MLPA and next generation sequencing were unable to identify this variant. In a family affected by intellectual disability, Saphyr identified a single de novo deletion affecting the NSF gene, undetected by chromosomal microarray, whole exome and whole genome sequencing and long read sequencing. This deletion was confirmed to be de novo in the child through PCR validation. Finally, Dr. Hoischen provided an update on his retrospective comparative study on leukemias, which he presented at ESHG 2020 and is expected to be submitted for peer-review publication in the near future. The study showed 100% concordance between Bionano’s Saphyr system and standard cytogenetics in 48 leukemia patients. Additionally, Saphyr identified novel events previously undetected by traditional cytogenetic methods, many of them being rare inter-chromosomal translocations causing gene fusions never described before, opening potential new avenues of research in precision medicine and drug development. Dr. Hoischen concluded that Saphyr has value in solving unanswered rare disease cases and has the potential to replace classical cytogenetics methods.At the ESHG 2020 conference, Dr. Uwe Heinrich, representing MVZ Martinsried, Germany presented that Bionano was able to confirm all known large rearrangements in a cohort of patients with intellectual disability, developmental disorders and chromosomal aberrations. Drs. Hoischen and Heinrich announced that their respective teams are planning to seek accreditation for the Saphyr system, to start offering Bionano’s genome imaging as part of a stepwise diagnosis, and to subsequently replace chromosomal microarray with Saphyr altogether later on.Erik Holmlin, Ph.D., CEO of Bionano Genomics commented: “We previously demonstrated the notable performance of Saphyr in leukemia studies across the globe, but the international study presented by Dr. El Khattabi demonstrates that Saphyr performs equally well in genetic diseases such as intellectual disabilities and subfertility. Saphyr showed 100% concordance with traditional cytogenetic methods and made additional discoveries in both leukemia patients and in those with constitutional disorders. We believe that Saphyr is capable of replacing traditional cytogenetic methods and consolidating these outdated methods into a single digital platform that is faster, less expensive and has lower manual labor needs, while providing greater accuracy than these methods.”A recording of the presentation by Drs.
