What Are Prenatal Genetic Screening Tests and How Should They be Interpreted?

In its recent article, “When They Warn of Rare Disorders, These Prenatal Tests Are Usually Wrong,” The New York Times published a discussion on the performance of prenatal blood screening tests. The piece, which also looked at the potential impact of results on patients, has fueled an online debate on medical ethics and misinformation. As a patient-centered health intelligence company with deep expertise in reproductive health and medical testing, we see this as a perfect opportunity to inform our partners on population health topics to help them better understand the accuracies (and inaccuracies) of clinical testing. In this guide, we aim to educate readers about the differences between screening and diagnostic tests and, crucially, why “positive” screening results should be interpreted as “further testing is recommended” and “negative” results as “no abnormalities detected; no further testing recommended.”

Improving Postpartum Hemorrhage Risk Prediction Through Machine Learning

Sema4 is committed to providing science-driven insights and solutions to address the most pressing medical needs. In collaboration with clinicians from the Mount Sinai Health System, we recently published two studies demonstrating the utility of machine learning to predict clinical outcomes for postpartum hemorrhage (PPH), the world’s leading cause of maternal death.

PPH is a preventable medical emergency resulting in excessive blood loss during or after delivery, with or without clinical symptoms. With one to 10 percent of deliveries at risk, PPH is among the top five causes of maternal death globally. It accounts for around a third of maternal deaths and often occurs in patients with no known risk factors for hemorrhage. While PPH is preventable, inconsistent diagnostic guidelines and risk assessment tools make the condition difficult to recognize, diagnose, and adequately address promptly to prevent maternal mortality.

I also assist and guide patients by counseling them on Sema4’s Noninvasive Prenatal Screening and its benefits, through screening and detection of possible risks for potential chromosome abnormalities in their current pregnancy. I focus on informing, guiding, and supporting patients throughout their planning and pregnancy journey, which helps them make informed decisions based on their test results.

Equity in Carrier Screening: What do ACMG’s New Guidelines Mean for Patients and Providers?

The American College of Medical Genetics and Genomics (ACMG) recently updated its guidelines on preconception and prenatal carrier screening. In this blog post, we explore these updates and hear from Dr. Marra Francis, Head of Medical Affairs for Women’s Health at Sema4, on what they mean for patients and providers.

Carrier screening is a type of genetic testing that can help individuals understand their risk of passing on a genetic condition to their child.​ The test analyzes a patient’s DNA to see if they are a carrier of a genetic variant (or change) that could cause an inherited disease in their children. You can learn more about carrier screening here. Medical societies, such as the American College of Obstetricians and Gynecologists (ACOG), recommend that carrier screening be offered to all women who are pregnant or planning for pregnancy.​ Similarly, ACMG’s position statement, first published in 2013, linked the utility of carrier screening to reproductive decision-making.

ACMG’s 2021 practice resource replaces their 2013 statement and uses more recent evidence to answer emerging questions clinicians and patients should consider during carrier screening. The updated guidance covers optimal panel size, the conditions that should be included, the use of pan-ethnic versus ethnicity-specific panels, the importance of pre- and post-test genetic counseling, and the need for a consistent and equitable approach to offering carrier screening to patients.

Sema4 and Beat Childhood Cancer Partner for Precision Oncology Advances

September is Pediatric Cancer Awareness Month. Sema4 is proud to partner with Beat Childhood Cancer Foundation (BCC), a nonprofit organization, as part of our goal to enable personalized treatment to transform pediatric cancer care.

BCC’s mission is to use precision medicine to bring forward new therapies for children with cancer with the goal of finding a cure for these patients.

In this interview with Beat Childhood Cancer Foundation Founder Patrick Lacey, we cover cancer care, the future of genomics, and what needs to change in the field of pediatric oncology.

Q: What was the impetus for creating the BCC research consortium and the foundation?

Patrick: When I was a first-time father with a six-month-old, my son was diagnosed with cancer and, in the next 18 months, we did everything possible to help cure him. We then were told we had exhausted all options, to take him home and give him quality days. My son had just turned two years old and that was not the answer we wanted to hear. As we looked at other options available, it was a bleak landscape. We wanted  to create an organization with a goal of creating treatment options for families.
