Ghent Criteria [hot]

Thus, the Ghent Criteria are first, genetic second.

The criteria were revised in 2010 (often called the ) to make diagnosis more specific and reduce misdiagnosis with similar conditions like Loeys-Dietz or Ehlers-Danlos syndromes. ghent criteria

The Revised Ghent Criteria elevated the importance of the FBN1 gene test. However, here is the catch: You can have a FBN1 mutation without having Marfan syndrome (a condition called "MASS phenotype"). Conversely, in very rare cases, the genetic test comes back negative, but the patient clearly has MFS clinically. Thus, the Ghent Criteria are first, genetic second

No diagnostic tool is perfect. Critics note that the Ghent Criteria may struggle with "overlap syndromes" where patients have mild aortic dilation and skeletal features but no clear FBN1 mutation. Furthermore, the reliance on Z-scores can be tricky in very tall or very short individuals, as body surface area calculations can vary.

While skeletal features can be subjective, lens dislocation is a binary, objective finding. It is present or it is not. This makes it a powerful diagnostic marker.
