We describe a male neonate with severe arachnodactyly, hypermobility of the fingers, flexion contractures of elbows, wrists, hips, and knees, micrognathia, crumpled ears, rockerbottom feet, loose redundant skin, and ocular abnormalities. Severe cardiac valve insufficiency and aortic dilatation resulted in cardiac failure and death 20 hours after birth. This case represents the severe end of the clinical spectrum of Marfan syndrome. As similar patients have been reported, they may represent a separate mutation.

An infant girl with arachnodactyly, spontaneously resolving contractures, dolichostenomelia, iridodonesis, and mitral and tricuspid incompetence died in cardiac failure. We confirm that congenital contractural arachnodactyly may exhibit serious cardiovascular and ophthalmic complications like Marfan's syndrome. The presence of iridodonesis further obscures the differentiation between classical Marfan's syndrome and congenital contractural arachnodactyly.

We reported six patients with Marfan's syndrome, studied retrospectively from May 1990 to April 1992 in the department of Cardiology in Dakar. Morphological, cardiovascular, skeletal and ocular abnormalities have been reviewed. All the patients had been evaluated by echocardiography. Prevalence of Marfan's syndrome among congenital heart diseases during this period was 4.8%. The mean age was 27.6 years. The mean height was 1.80 m (range 1.38-2.02 m) for a mean weight of 62.8 kg. All the patients had dolichostenomely and arachnodactyly. Kyphosis or scoliosis was present in 5 cases. Chest deformities (pectus carinatum and excavatum) were present in 5 cases. 5 patients had hyperextensible joints. 5 patients had ocular abnormalities. Cardiac pathology was found in 5: mitral prolapse with insufficiency in 2; mitral prolapse with aortic dystrophy in 2; and isolated dilatation of ascending aorta in an other. One patient with diffuse Marfan's syndrome died of cardiac failure. Our study confirm polymorphic manifestations of Marfan's syndrome and the frequency of cardiac abnormalities which are the major determinants of life-prognosis in these patients. Echocardiography is very useful as a noninvasive method for defining the extent of cardiovascular involvement and following its course, for more appropriate treatment.

An infant with neonatal Marfan syndrome is described who presented with arachnodactyly, distinctive dysmorphic features and prolapse of both atrioventricular valves and dilatation of both the aortic and pulmonary root. She died in cardiac failure shortly after pacemaker implantation, due to dysrhythmia and severe mitral insufficiency. At autopsy, apart from myxomatous changes of the valves and dilated aortic and pulmonary roots, an aneurysm of the sinus of Valsalva of the pulmonary valve and abnormal myxomatous connective tissue surrounding the AV node were also found. Molecular genetic studies showed a point mutation in the fibrillin 1 gene that creates a new N-glycosylation site, which has been described once before.

We report a series of 9 children with neonatal Marfan syndrome. The diagnosis was made on a striking facial dysmorphia associated with arachnodactyly type skeletal anomalies. They all had cardiovascular anomalies: aortic dilatation 9 times, and mitral and/or tricuspid valve prolapse 8 times. Three children underwent ascending aorta replacement with the Yacoub technique. There was one operative death in a young infant and the two survivors required further surgery for gross mitral insufficiency and an aneurysm of the horizontal aorta. Three children died before the age of 1 year from cardiac insufficiency linked to massive leaks of all the valves. The three youngest children in the series did not undergo any procedure and were followed up for a slowly growing dilatation of the initial aorta. The prognosis of neonatal Marfan syndrome is weighted with a heavy mortality. The timing of surgical intervention in case of excessive dilatation of the aortic root is difficult to determine. It depends not only on the aortic diameter but also on the aortic valve function and the existence of other mitral or tricuspid lesions. Surgical treatment for lesions of the initial aorta and the atrioventricular valves improves the short-term prognosis but the risk of re-intervention is higher.

Neonatal Marfan syndrome caused by an exon 25 mutation of the Fibrillin-1 gene: We describe a male infant with severe arachnodactyly, hypermobility of the fingers, flexion contractures of elbows, wrists, hips, and knees, microretrognathia, crumpled ears, rockerbottom feet, loose redundant skin, and lens dislocations. 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.

To investigate the sudden death of a 36-year-old Chinese man, a medicolegal autopsy was performed, combining forensic pathological examinations and genetic sequencing analysis to diagnose the cause of death. Genomic DNA samples were extracted from blood and subjected to high-throughput sequencing. Major findings included a dilated aortic root with a ruptured and dissected aorta and consequent tamponade of the pericardial sac. Moreover, arachnodactyly and other skeletal deformities were noted. By sequencing the fibrillin-1 gene (FBN1), five genetic variations were found, including four previously known single nucleotide polymorphisms (SNPs) and a novel frameshift mutation, leading to the diagnosis of Marfan syndrome. The frameshift mutation (c.4921delG, p.glu1641llysFsX9) detected in exon 40 led to a stop codon after the next 8 amino acids. The four SNPs included a splice site mutation (c.3464-5 G>A, rs11853943), a synonymous mutation (p.Asn625Asn, rs25458), and two missense mutations (p.Pro1148Ala, rs140598; p.Cys472Tyr, rs4775765). Genetic screening was recommended for the relatives as it was reported that the father and brother of the deceased had died at the ages of 40 and 25, respectively, from sudden cardiac failure. The son of the deceased lacked the relevant mutations. This report emphasizes the important contribution of medicolegal postmortem analysis on the molecular pathogenesis study of Marfan syndrome and early diagnosis of at-risk relatives.
