Cardiac valve insufficiency and aortic dilatation resulted in cardiac failure, decompensated with digitalisation and death occurred at the age of 4 months. This case represents the severe end of the clinical spectrum of Marfan syndrome, namely neonatal Marfan syndrome. Molecular diagnostic analyses confirmed a de novo exon 25 mutation in the FBN1 gene.eninfo:eu-repo/semantics/closedAccessArachnodactylyEctopia LentisFBN1 GeneNeonatal Marfan SyndromeArticle152219225152874232-s2.0-3142588893N/AWOS:000222686500010Q4
