Genetic analysis of brain blood vessel malformations

Genetics of Central Nervous System Arteriovenous Malformations (AVM): Genotype-Phenotype Correlation and Prognostic Impact on Patients With AVM

Observational Fondation Ophtalmologique Adolphe de Rothschild · NCT04772963

This study is trying to see how certain genetic changes might affect the development and outcomes of brain blood vessel malformations in patients who have them.

What this trial studies

This observational study focuses on understanding the genetic, molecular, and cellular mechanisms behind cerebral and medullary arteriovenous malformations (AVMs). It aims to investigate the influence of genetic mutations on the prognosis of AVMs, particularly in cases that are not linked to hereditary conditions. Patients with diagnosed vascular malformations will provide blood samples for genetic analysis, which may help clarify the role of specific mutations in AVM development and outcomes. The study is conducted at the Hôpital Fondation Adolphe de Rothschild in Paris.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with cerebral or medullary vascular malformations who are undergoing clinical monitoring or intervention.

Not a fit: Patients who are pregnant, parturient, or breastfeeding will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of arteriovenous malformations, potentially enhancing patient outcomes.

How similar studies have performed: While some studies have explored genetic factors in vascular malformations, this specific approach focusing on AVMs is relatively novel.
