IRVINE, Calif., Oct. 14, 2014 (GLOBE NEWSWIRE) -- CombiMatrix Corporation (Nasdaq:CBMX), a molecular diagnostics company specializing in DNA-based testing services for pre- and postnatal developmental disorders, today announced data from a comprehensive, multi-year analysis of products of conception (POC) testing by chromosomal microarray analysis (CMA) showing that CMA yields a successful result in more than 85% of cases. Trilochan Sahoo, M.D., Director of cytogenetics at CombiMatrix, will present results at the American Society of Human Genetics (ASHG)'s 64th Annual Meeting on Monday, October 20, 2014 in San Diego, California.
CombiMatrix analyzed 3,408 consecutive specimens that included both fresh POC tissue and archived formalin-fixed, paraffin-embedded (FFPE) samples. Results showed that 2,345 out of 2,712 (86.5%) fresh POC samples and 492 out of 564 (87.2%) FFPE samples provided a successful result, with common reasons for test failure including insufficient sample size and poor DNA quality.
“Chromosomal abnormalities account for more than half of all first trimester pregnancy losses, and determining the cause of pregnancy loss can assist in providing appropriate medical management and recurrence risk counseling to patients,” said Dr. Sahoo. “Classical cytogenetic analysis of POC using karyotyping requires the successful culture of a fresh POC specimen and yields a successful result 60% of the time, on average, depending upon sample type. In contrast, CMA enables the direct analysis of both fresh and archived POC tissue, requiring only genomic DNA, and yields a successful result more often, thus offering meaningful advantages over the traditional methodology.”
For the study, CombiMatrix used three CMA platforms – BAC-aCGH, oligo-aCGH and single nucleotide polymorphism (SNP) array. Of the three platforms, the SNP array had the highest abnormality detection rate (53.8%) and, in addition to chromosomal imbalances, also identified cases with whole genome or multiple regions of allelic homozygosity.
“At CombiMatrix, we are committed to making technological and scientific advancements while concurrently growing commercially,” said Mark McDonough, President and Chief Executive Officer of CombiMatrix. “Our laboratory and scientific team are experts at handling and testing FFPE tissue, and this capability differentiates CombiMatrix and our CMA offering from other cytogenetics labs. The results of this analysis that we will present at ASHG validate the added benefits of the high-resolution, genome-wide SNP array, which is the platform that underlies our current test offerings.”
