Loeys-Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder characterized mainly by cardiovascular, craniofacial and skeletal features. We report on a patient with LDS, whose prenatal examination was compatible with the diagnosis of arthrogryposis multiplex congenita. Neonatal assessment showed craniofacial and cardiovascular findings suggestive of LDS whose diagnosis was confirmed by the detection of a novel mutation (HGVN: NM_003242.5 (TGFBR2): c.1381T > C (p.(Cys461Arg))) in the TGFBR2 gene. Few prenatal and neonatal cases of LDS have been reported in the literature. We reviewed all cases reported to date with perinatal onset to delineate the clinical manifestations that allow us to prompt diagnosis of this syndrome at an early stage to prevent fatal cardiovascular complications. Furthermore we discuss the multidisciplinary follow up required in these patients.
