Bionano Genomics, Inc. (Nasdaq: BNGO) today announced the publication of a peer-reviewed study evaluating optical genome mapping (OGM) as a method for investigating abnormal noninvasive prenatal testing (NIPT) results because of its ability to accurately identify complex structural aberrations relevant to recurrent pregnancy loss and infertility.

In a case study from Hangzhou Maternity and Child Care Hospital, researchers analyzed samples from a pregnant subject who had an abnormal NIPT result in her second pregnancy, after experiencing a spontaneous abortion the prior year. The study sought to determine OGM’s utility for detection of chromosome breakages and fusions found in complex chromosomal rearrangements (CCR), which can significantly increase an abnormal pregnancy outcome for carrier couples. The study reports that about 70% of CCR carriers are phenotypically normal, but they have a high risk of recurrent miscarriage, subfertility or infertility, and pregnancy abnormalities due to conceiving offspring with unbalanced CCRs.

The researchers used OGM as part of a confirmatory workflow after amniocentesis, karyotyping (KT), and chromosomal microarray analysis (CMA) identified suspected structural rearrangements with unknown origins, believed to indicate a CCR event. The study reported that OGM revealed complex structural aberrations that KT and CMA did not identify, confirming the subject as a carrier of a CCR involving three chromosomes and four breakpoints, and thereby aiding researchers in subsequent prenatal diagnosis and genetic counseling.

Erik Holmlin, PhD, president and chief executive officer of Bionano commented, “We are pleased to see the study provide validation of OGM’s potential utility for prenatal analysis and show how OGM may help researchers understand the underlying genetic etiology of recurrent miscarriage or pregnancy abnormalities. We believe OGM could be used as a comprehensive follow-up genome analysis in cases with a positive NIPT screen or for some high-risk pregnancies.”
