Summary

This study looked at hospital records from 2015 to 2022 to find out how many people in France have a group of rare genetic conditions called PROS. Researchers counted new cases each year, described patient ages and other health problems, and estimated costs. No treatments were tested—the goal was simply to learn more about who is affected and how the disease is managed in hospitals.
