Natera, a San Carlos, California-based provider of non-invasive genetic testing and circulating cell-free DNA analysis, announced that the company’s Panorama Non-Invasive Prenatal Test (NIPT) is now certified to detect zygosity (identical or not identical). /fraternal) in twin pregnancies. for: and chromosomal abnormalities.
Natera’s Panorama is the first NIPT that can determine whether twins are monozygotic (identical) or fraternal (non-identical or fraternal) at 9 weeks gestation. In validation studies, Panorama detected monozygotic twins with greater than 99% sensitivity and specificity.
Natera Cancer Genetic Testing
Accurate assessment of zygosity early in twin pregnancy is important. Monozygotic pregnancies may be at risk for complications arising from monochorionicity (shared placenta). About 67% of monozygotic pregnancies are also monochorionic pregnancies, which are at the highest risk for intrauterine growth restriction, birth defects, and twin-to-twin transfusion syndrome, a complication of unequal blood supply that results in morbidity and high mortality.

Until now, expectant parents and their doctors have been faced with unanswered questions early in their twin pregnancy. Sometimes it is difficult to determine chorionicity, especially when the pregnancy approaches the second trimester. In fact, studies have shown that up to 19% of monochorionic pregnancies are misclassified as dichorionic and cannot be properly managed.
“Panorama now fills a significant unmet need for parents and physicians managing twin pregnancies,” said Matthew Rabinowitz, MD, CEO and founder of Natera. “Improving the spectrum to include twin pregnancy screening is an important advance that can identify zygosity at an earlier stage and help doctors identify the highest risk for conditions that affect more than 1 in 45 twin pregnancies 1 . ” This new opportunity builds on the success of Panorama, the market-leading NIPT for common chromosomal conditions.”
Panorama builds on its history as the only NIPT that can distinguish the DNA of mother and child by becoming the only NIPT that can now distinguish the DNA of any twin. This unique technology enables Panorama to determine the zygosity and gender of each twin. It also helps identify the risk of more genetic conditions in twin pregnancies than other NIPTs, including monosomy X, sex chromosome trisomies, and 22q11.2 deletion syndrome (for monozygotic twins only). endometrial cancer, ovarian cancer and some other types of cancer. Lynch syndrome is the most common inherited cause of colon and endometrial cancer. Doctors estimate that 3 out of every 100 cases of colon or endometrial cancer are caused by Lynch syndrome.

Watch our webinar, “Lynch Syndrome and Women’s Health: How to Identify and Manage Inherited Cancer Risk,” which includes a comprehensive discussion between a gynecologist and medical director, a professor of public health and a genetic counselor, and a liaison manager of medical science.
Because the two most common types of Lynch syndrome cancers occur in the female reproductive tract, obstetricians, gynecologists, and gynecologic oncologists are uniquely positioned to identify women at significant risk for Lynch syndrome.
In addition to the increased risk of colorectal cancer, women with Lynch syndrome are at higher risk of developing endometrial and ovarian cancer than the general population. Gynecological cancer can often be the first cancer diagnosed in women with Lynch syndrome.
Not all Lynch syndrome carriers develop cancer. Most of those related to Lynch syndrome have a high survival rate if detected early, and some can even be prevented. Genetic test results can improve outcomes by providing early and increased access to screening and risk reduction options.
Lynch Syndrome And Hereditary Cancer
My grandmother died of breast cancer and my father was diagnosed with colon cancer before he was 50. My entire family was immediately tested by the patient and BRCA negative. I naively assumed this meant I had no other genetic mutations. A few years later, my doctor advised me to have a full panel genetic test. That’s when I found out I had Lynch syndrome.
People who have Lynch syndrome have an increased risk of developing many types of cancer, including endometrial, colorectal, ovarian, stomach, pancreatic, brain, or small bowel cancer. When a patient knows they have the genetic mutation associated with Lynch syndrome, they can begin surveillance and choose risk-reduction options earlier, increasing lifetime survival rates.
Join an exclusive conversation with Professor Deborah Cragun (Lynch Syndrome Screening Network), Dr. Amber Shamburger and Kathy Young, MS, CGC, to learn:
I feel like the luckiest person in the world to have this information. I may have been before. Now I can take control of my health and make sure I never have to deal with uterine or colon cancer like every other woman on my maternal line has.

The FDA designation will help expedite the agency’s evaluation and review of Signatera as an in vitro diagnostic for use in pharmaceutical trials.
The Signatera methodology differs from currently available liquid biopsy tests that screen for a fixed panel of therapeutically important genes. Signatera is the first ctDNA test that is tailored to each patient based on the unique mutations in an individual patient’s tumor. Signatera provides each individual with a personalized blood test tailored to match the clonal mutations found in that individual’s tumor tissue. This process maximizes the accuracy of detecting the presence or absence of measurable residual disease (MRD) in a blood sample, even at the levels of a single mutant molecule in a blood vessel. Signatera also enables researchers to track additional mutations of interest, up to several hundred mutations, for clinical studies.
Several clinical studies have shown that Signatera is able to detect residual measurable disease up to 2 years earlier than standard imaging.

Studies have also shown the test’s usefulness in bladder, breast, colorectal and non-small cell lung cancer. Signatera test status is the most important predictor of long-term patient outcomes after surgery and treatment compared to all other clinical and pathologic factors.
“This important device designation is an important step forward in our commercial strategy to help Natera participate in drug registration trials that use Signatera for patient selection and study enrichment,” said Solomon Moshkiewicz, general manager of oncology and transplantation. businesses in Natera. “This milestone directly supports our stated goal of achieving $40 million to $50 million in cumulative pharmaceutical contracts by the end of 2019.”
“We are pleased to work with the FDA in the context of a breakthrough device program,” said Natera CEO Steve Chapman. “This designation confirms our belief that Signatera will truly change the way cancer patients are diagnosed and treated, ultimately leading to better
