French hospital data reveals hidden burden of rare PROS disorders
NCT ID NCT07222423
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.

Inclusion criteria: Population P1 was identified using a combined query, considering: * International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes for PROS-related malformations; OR * PROS-related technical procedures performed during hospitalizations to relieve the symptoms of the disease. Subpopulation SP1 was identified through the identification of at least two PROS-related hospitalizations (PROS-related ICD-10-CM or technical procedure code), including the index hospitalization. Exclusion criteria: Presence at any time during the entire study period of: * ICD-10-CM codes for chromosomal malformation; OR * ICD-10-CM code for hemangioma to avoid inclusion of patients with hemangioma and other vascular malformation; OR * ICD-10-CM codes associated with the following comorbidities: cancer, cerebrovascular pathologies, hemiplegia (for pediatric patients only), metastatic pathologies, or myocardial infarction.
