preimplantation genetic diagnosis

First Genetics will market its F-Genetics NGS System and IVD assays to Russian laboratories for reproductive health testing and cancer diagnostics.

The Cyprus-based company has been offering a cell-free DNA-based noninvasive prenatal test for fetal aneuploidies, called Veracity, since 2015.

Researchers tested the combined PGS and PGD assay in a pilot study and now aim to validate it on larger numbers of disorders and compare it to conventional testing.

Cooper took a $24.4 million impairment charge in the second quarter on the intangible assets it acquired in 2016 from carrier screening firm Recombine.

According to John Zhang, founder and CEO of the New Hope Fertility Center, universal PGS will likely increase success rates of IVF further.

A study by researchers in Italy found that preimplantation genetic diagnosis and screening combined led to more successful pregnancies per transfer but fewer women had embryos transferred.

The genetic diagnostics firm has developed an NGS-based test that combines PGS, PGD, and informativity testing, and presented initial results at a recent conference. 

The team built on a previous approach that used single-cell sequencing to screen for chromosomal abnormalities in embryos from couples undergoing IVF.

The firm plans to incorporate mtDNA analysis into its preimplantation genetic screening services this month.

The method could have future applications in preimplantation genetic diagnosis and circulating tumor cell analysis.
