It is described the occurrence of dextrocardia together with the congenital cyanotic heart disease in 20 year old man included in the fruste forme of the Marfan's syndrome. The diagnosis was made by the physical examination with the evidence of the arachnodactyly by the metacarpal indices and confirmed by autopsy with the following results: dextrocardia, large atrial septal defect, common ventricle, atresia of the pulmonary artery with the collateral lung perfusion from the descending aorta. There were found neither ocular manifestations, nor unambiguous manifestations of the aortic lesions. The ultrastructural examinations showed only greater accumulation of the PAS positive substances. Dextrocardia as the cardiovascular manifestation of the Marfan's syndrome has not yet been reported in the available literature.

A premature infant with arachnodactyly and congenital cyanotic heart disease had severe pulmonary emphysema, a little-known manifestation of Marfan syndrome. The possible etiologies of emphysema in this syndrome are discussed.

A 5-month-old girl with Marden-Walker syndrome is presented. This is a rare autosomal recessive syndrome. So far, approximately 20 cases have been described in the literature. The patient was hospitalized because of difficulty in feeding and slow spontaneous movements. Her parents were first cousins. She was diagnosed with clinical findings of growth and motor retardation, typical facial appearance, congenital heart disease, arachnodactyly, joint contractures, and a Dandy-Walker malformation on magnetic resonance imaging.

We report two sibs of consanguineous parents with multiple congenital abnormalities which include prenatal and postnatal growth retardation, anterior segment defects of the eye, arachnodactyly with other skeletal abnormalities, congenital heart disease and early lethality. We think this constellation of anomalies may represent a previously undescribed syndrome. There are some similarities to Michels syndrome from which it should be differentiated.

Prader-Willi syndrome is characterized by hypotonia and feeding difficulties in the neonatal period, with the childhood development of hyperphagia leading to obesity, developmental delay, hypogonadism, short stature and small hands and feet. Correct diagnosis of Prader-Willi syndrome is important because of its clinical implications and the need for family genetic counseling. In order to determine the most efficient method of diagnosing the condition, we evaluated 37 patients with a putative diagnosis of Prader-Willi syndrome by both clinical and molecular cytogenetic analyses. Clinical evaluation showed that 25 patients fulfilled the diagnostic criteria for Prader-Willi syndrome. A deletion of the region 15q11.2-13 was cytogenetically identified in 20 patients using a high-resolution technique. Four additional cases were detected by fluorescence in situ hybridization (FISH) with the cosmid probes for D15S11, r-aminobutyric acid receptor beta 3 (GABRB3), small nuclear ribonucleoprotein-associated peptide N (SNRPN) or D15S10 (Prader-Willi/ Angelman syndrome region probes). The deletion of SNRPN was documented in 24 Prader-Willi syndrome patients. Only one additional patient with typical Prader-Willi syndrome features did not have any deletion over 15q11-13 at either the cytogenetic or molecular level. FISH provides a more reliable method than high-resolution chromosome analysis for the diagnosis of Prader-Willi syndrome. Associated conditions such as hypopigmentation, small-joint laxity, arachnodactyly, seizure disorder, optic atrophy, congenital heart disease, Perthes' disease, hirsutism, astigmatism/amblyopia, microcephaly and neuropsychiatric disturbances dictate the effects of a contiguous gene syndrome. Morbidity is high among patients with obesity and associated conditions. Appropriate genetic counseling should be given to the parents and dietary management should be helpful for patients with Prader-Willi syndrome.

Congenital contractural arachnodactyly (CCA) is an autosomal dominant condition that shares skeletal features with Marfan syndrome (MFS), but does not have the ocular and cardiovascular complications that characterize MFS. CCA and MFS result from mutations in highly similar genes, FBN2 and FBN1, respectively. All the identified CCA mutations in FBN2 cluster in a limited region similar to where severe MFS mutations cluster in FBN1, specifically between exons 23 and 34. We screened exons 22 through 36 of FBN2 for mutations in 13 patients with classic CCA by single stranded conformational polymorphism analysis (SSCP) and then by direct sequencing. We successfully identified 10 novel mutations in this critical region of FBN2 in these patients, indicating a mutation detection rate of 75% in this limited region. Interestingly, none of these identified FBN2 mutations alter amino acids in the calcium binding consensus sequence in the EGF-like domains, whereas many of the FBN1 mutations alter the consensus sequence. Furthermore, analysis of the clinical data of the CCA patients with characterized FBN2 mutation indicate that CCA patients have aortic root dilatation and the vast majority lack evidence of congenital heart disease. These studies have implications for our understanding of the molecular basis of CCA, along with the diagnosis and genetic counseling of CCA patients.

Distal duplication, or trisomy 15q, is an extremely rare chromosomal disorder characterized by prenatal and postnatal overgrowth, mental retardation, and craniofacial malformations. Additional abnormalities typically include an unusually short neck, malformations of the fingers and toes, scoliosis and skeletal malformations, genital abnormalities, particularly in affected males, and, in some cases, cardiac defects. The range and severity of symptoms and physical findings may vary from case to case, depending upon the length and location of the duplicated portion of chromosome 15q. Most reported cases of duplication of the long arm of chromosome 15 frequently have more than one segmental imbalance resulting from unbalanced translocations involving chromosome 15 and deletions in another chromosome, as well as other structural chromosomal abnormalities. We report a female newborn with a de novo duplication, 15q24-q26.3, showing intrauterine overgrowth, a narrow asymmetric face with down-slanting palpebral fissures, a large, prominent nose, and micrognathia, arachnodactyly, camptodactyly, congenital heart disease, hydronephrosis, and hydroureter. Chromosomal analysis showed a 46,XX,inv(9)(p12q13),dup(15)(q24q26.3). Array comparative genomic hybridization analysis revealed a gain of 42 clones on 15q24-q26.3. This case represents the only reported patient with a de novo 15q24-q26.3 duplication that did not result from an unbalanced translocation and did not have a concomitant monosomic component in Korea.
