#348: NIPT Beyond the Basics: Screening for Single-Gene Conditions

Prenatal screening has transformed over the past decade, with Non-Invasive Prenatal Testing, or NIPT, becoming a go-to tool for early risk assessment. But even as adoption increases globally, we’re still facing real gaps, from limited condition coverage to a lack of support in interpreting results.

On this episode, I’m joined by Dr. Fred Ushakov, a renowned fetal medicine expert based in London. We are going to explore how NIPT is evolving and how a next-generation screening tool like Fulgent’s KNOVA is pushing the boundaries of early detection.

We’ll also dive into how structural scans and single-gene conditions factor into smarter screening strategies, and what patients and providers alike need to know when choosing the right test.

What We Cover in This Episode:

• The current state of NIPT access and adoption in the UK (public vs. private healthcare)
• Clinical blind spots in traditional NIPT; and how they impact patients
• How KNOVA is expanding prenatal screening with 56 genes, associated with 30+ monogenic conditions
• Why structural ultrasound and NIPT are complementary tools, not replacements
• How the SMART Test® NIPT algorithm enhances precision and timing of risk detection
• Early detectable conditions on KNOVA (e.g., Noonan syndrome, skeletal dysplasias)
• Conditions not typically visible on ultrasound (e.g., Rett syndrome, CHARGE)
• What providers and patients should know when considering an expanded NIPT
• Dr. Ushakov’s insights on the future of prenatal screening innovation

We want to thank Fulgent for sponsoring this episode. All of our episodes, including this one, are for informational purposes only and do not constitute medical advice. Please consult a healthcare provider for personalized guidance. KNOVA is a screening test and not diagnostic. All results should be confirmed with diagnostic testing and interpreted with the support of a healthcare provider like a genetic counselor.

Furthermore, Dr. Ushakov served as an Ambassador of the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) in 2014-2020.

He has a particular interest in the training and support of doctors and sonographers in other countries to help them to protect and preserve the health of mothers and unborn babies.
