We all play different roles in our lives: We are friends, children, siblings, parents, cousins, employees, and more. In each of these roles, we assume the jargon of that role when we talk in those environments. In our workplaces, we may use the scientific, technical, or specific jargon…
Mutations & Conversations
— Tré LaRosa

Tré LaRosa is a scientific project manager, patient advocate, and writer. He has cystic fibrosis (CF) and carries two copies of the F508del mutation. He’s been on Trikafta since 2019. He writes about science, living with CF, grief, family, and everything in between in an effort to get you thinking about what it means to be human. He lives in Arlington, Virginia with his fiancée Jessica and their two wonderful, lazy dogs, Duncan and Leo. He enjoys playing sports, being outdoors, and reading — and especially buying more books.
My column, “Mutations & Conversations,” was first launched in 2018 after I observed Cystic Fibrosis Awareness Month by writing a blog post every day in May about living with cystic fibrosis (CF). This decision to write this series was made in the midst of grief: My sister,…

For nearly three years, I’ve worked alongside brilliant CF doctors, scientists, and PhDs at a great research hospital. Before that, during college, I worked closely with CF scientists and PhDs at the University of Kentucky. All in all, I have about five years of experience in CF science.
The CF community’s strength is in its powerful, far-spread voice. For people with a chronic disease, and doubly so when that chronic disease is rare like CF, it is critical for the community to be involved and educated. The CF community is exactly that. When a perfect storm…
Let’s Talk About Death and Grief
I consider myself a conversation-starter. I like discussing serious topics and sharing my genuine feelings and thoughts with others. I enjoy talking about sports, engaging in light banter, and dissecting the plots of TV shows — even why “The Bachelor” or “The Bachelorette” made the wrong choice. I’m…
I walk two paths: One is that of logic in my career as a scientist. In this field, it’s critical to remove emotion from the picture as much as possible. I work as a cystic fibrosis (CF) scientist so that isn’t always easy, but it is important. The…
The Power of Escapism
One of the first fiction books I read in adulthood was a book called “The Amazing Adventures of Kavalier & Clay,” by Michael Chabon. The story of how I came across “Kavalier & Clay” begins in high school. In my senior literature class, we had to write…
During my sophomore year of college, the background on my computer screen was a cystic fibrosis transmembrane conductance regulator (CFTR) protein, specifically a visualization of its quaternary structure. It looked something like this image. The simplified graphic isn’t an exact representation of what the CFTR protein looks…
In high school, I aspired to be a pulmonologist for obvious reasons: I wanted to aid the CF community by directly helping patients. It seemed logical. I dreamed of becoming a pulmonologist because my CF doctors had been some of my greatest role models. They were quite literally…
My Family Had 2 Children with CF
It was unlikely that my parents would bear two children with CF. When both parents carry a CF mutation but don’t have the disease itself, there is a 1 in 4 chance that a child will have CF. To determine the likelihood of two events independent of one…
My Thoughts on Exercise and CF
It’s hard to understate the benefits of exercise for healthy people, let alone people with CF. According to the Mayo Clinic, some of these benefits include: It controls weight. It combats health conditions and diseases. It improves mood. It boosts energy. It promotes better sleep. All of these…
A couple of months ago, I did back-of-the-envelope calculations on basic CF stats. Here’s what I asked: In a year, how much time do I spend doing treatments? How many pills do I take? As I wrote last week, the spectrum of CF presentation is about as…
If you’ve ever met more than one person with cystic fibrosis, it’s likely they had very different experiences than you. First, their approach likely will be different; chronic disease affects everyone differently mentally, so some are vocal and “embrace” it, while others are quieter and choose to consider it a…
