Table 1.

A simplified table for the diagnosis of Marfan syndrome based on the revised Ghent criteria^*

Criteria	Aortic dilation	Ectopia lentis	Systemic features	Family history	FBN1 mutation
Aortic dilation	-	MFS	MFS	MFS	MFS
Ectopia lentis	MFS	-	-	MFS	MFS*;
Systemic features	MFS	-	-	MFS	-
Family history	MFS	MFS	MFS	-	-
FBN1 mutation	MFS	MFS ‡	-	-	-

^*Some combinations of at least two features out of 5 confirm the diagnosis (marked by MFS). See text for more explanation

^‡Only FBN1 mutations with known risk for aortic dissection are acceptable
