#228 Trisomy 13 and Trisomy 18 with Divya Ramachandra

DNA Today: A Genetics Podcast

Update: One of our recurrent guests genetic counselor and fellow podcaster Laura Hercher had a couple important thoughts after listening to our episode we want to share. Laura has been a guest on Episodes 157 & 191 where she has shared her insight on abortion bans including Texas SB 8 and the overturn of Roe v. Wade.

“I understand the reasons for moving our language away from terms like ‘lethal’ or ‘incompatible with life’, but we are also now faced with multiple states where only a lethal anomaly or condition is considered grounds for a legal abortion (insurance coverage for the abortion may hinge on this as well). And in fact, the language is so strict and the consequences so concerning that many institutions are basically turning down virtually all exceptions. It's a giant mess. So, not saying that it isn't important to tell the truth -- of course! But that term ‘lethality’ may need to remain in the conversation even when survival isn't out of the question.”

Thanks Laura for writing in and adding to our conversation and considerations with the complexities surrounding reproduction.

Our guest today is Divya Ramachandra, who is a genetic counselor and program coordinator in Chicago, practicing primarily in prenatal, pediatric, and inpatient genetics. In this episode, she provides us with a comprehensive overview of trisomy 13 (T13) and trisomy 18 (T18) and genetic counseling for these patient populations.

Divya presented at the National Society of Genetic Counselors’ Annual Conference this past fall titled “From Lethal to Life-Limiting: Paradigm Shift in Caring for Patients with Trisomy 13 or 18” which we covered in our NSGC 2022 recap episode (#212). She published her thesis in the Journal of Genetic Counseling on transitional challenges novice genetic counselors face after graduation. She has a strong interest in bioethics and serves on the Pediatrics Ethics Committee as well as the Genetics Ethics Service Line at her institution.

On This Episode We Discuss:

Symptoms of T13/T18

Signs on ultrasound that a pregnancy may have T13/T18

Surely you have heard of whole genome sequencing, but what about rapid and ultra-rapid whole genome sequencing? This is an emerging method of diagnosing genetic conditions for quick management. PerkinElmer Genomics offers this incredibly valuable test, which can be life saving for ill babies and kids. Learn more in our full episode (#226) with PerkinElmer Genomics.

As a listener of DNA Today, you probably heard me talk about NIPT, non-invasive prenatal screening, that looks for extra or missing chromosome conditions during pregnancy. But did you know there is one that can also screen for recessive disorders (like cystic fibrosis) and fetal antigens? BillionToOne offers UNITY Screen, which does all this from one blood draw from a pregnant person. Visit unityscreen.com for more info. Listen to DNA Today Episode #224 Single Gene NIPT and #225 Fetal Antigen NIPT. (Sponsored)
