1/389. Autosomal dominant secundum atrial septal defect with various cardiac and noncardiac defects: a new midline disorder.We report on a Lebanese family in which 12 persons had an atrial septal defect and various cardiac and noncardiac anomalies. Cardiac anomalies are left axis deviation of QRS, right bundle branch block, atrial fibrillation, wolff-parkinson-white syndrome, nodal atrioventricular rhythm, aortic stenosis, pulmonic valve stenosis, mitral stenosis (lutembacher syndrome), and low implantation of the tricuspid valve (Ebstein disease). Noncardiac abnormalities consisted specially of the presence of hypertelorism, cleft lip, and pectus excavatum. This combination appears to constitute a hitherto undescribed autosomal dominant midline disorder of the heart and upper half of the body with almost full penetrance and variable expressivity. The mutation does not map to any known locus involved in atrial septal defect or conduction block.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
2/389. Mutchinick syndrome in a Japanese girl.We report on a 7-year-old Japanese girl with Mutchinick syndrome, a rare congenital malformation syndrome described in a pair of Argentinean sisters and a pair of German brothers; both originating from the same geographic region in the former East prussia. The girl we describe had most of the clinical manifestations of the syndrome, including growth and developmental retardation, and craniofacial anomalies with microcephaly, hypertelorism, a broad straight nose, low-set malformed ears, and a wide, tented mouth. She also had the following hitherto undescribed manifestations: ventricular septal defect, palmoplantar hyperkeratosis, bilateral partial soft-tissue syndactyly of second and third toes, and megaloureters. The occurrence of the syndrome in a Japanese girl indicates that the syndrome is not restricted to the descendants of individuals from a confined region in northeastern europe.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
3/389. Frontonasal dysplasia, macroblepharon, eyelid colobomas, ear anomalies, macrostomia, mental retardation, and CNS structural anomalies. A new syndrome?We report a Brazilian girl, born to normal and non-consanguineous parents and presenting, among other signs, brachyacrocephaly, a wide forehead, hypertelorism, wide palpebral fissures with multiple eyelid colobomas, a broad and high nasal root, an absent nasal tip, a wide columella, a long and smooth philtrum, a carp-like mouth, macrostomia, a thin upper lip with midline notching, submucous cleft of the soft palate, a small and grooved chin, ear anomalies, Dandy-Walker anomaly, a structural anomaly of the corpus callosum, grey matter heterotopia, and mental retardation. The whole clinical picture of the present patient suggests a 'new' type of frontonasal dysplasia and main differential diagnosis includes the acrofrontofacionasal dysostosis 2 syndrome (MIM 201181). Other differential diagnoses are discussed.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
4/389. Multiple systemic and periocular malformations associated with the fetal hydantoin syndrome.anticonvulsants remain necessary during pregnancy and the removal of such drugs is not recommended. However, on the available evidence, the physician may expect an increased risk of malformation including eye abnormalities as has been outlined. The abnormalities include growth deficiencies and delayed motor/mental development together with dysmorphic features, the most common of which seems to be cleft lip/cleft palate. Additionally, many of these children suffer from eye abnormalities including hypertelorism, ptosis, strabismus, epicanthal folds, and in this case abnormalities of the lacrimal apparatus.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
5/389. Wolf's syndrome in twins -- translocation in the mother.A case of MZ twins, both affected by Wolf's syndrome, is described. Their mother, of subnormal look and low intellectual level is translocated. The children, born with a weight and size much below the average, show a very special morphotype; a hook-nose, an an abnormal conformation of the back edge of the nostrils (a protrusion in the shape of a horn overhanging the filtrum), hypertelorism, microcephaly. Great asynchronism in the maturation of the bones and a somatoschisis of the body of the cervical vertebrae are noted. Deletion of the short arm chromosome 4 is juxtacentromeric. The study of blood and tissue groups corroborates monozygosity. Dermatoglyphs are little abnormal and identical in the two children. The mother's family is phenotypically normal. At 19 months of age, measuring is still below 4, psychomotor progress is extremely weak, and convulsions are frequent.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
6/389. XLMR syndrome characterized by multiple respiratory infections, hypertelorism, severe CNS deterioration and early death localizes to distal Xq28.We report on a family with severe X-linked mental retardation (XLMR) and progressive, severe central nervous system deterioration. Three of the five affected males died of secondary complications before the age of 10 years and none have survived past the age of 10. These complications included swallowing dysfunction and gastroesophageal reflux with secondary recurrent respiratory infections. In addition, hypotonia and a mild myopathy were also present. All had a characteristic facies, including downslanting palpebral fissures, hypertelorism, and a short nose with a low nasal bridge. The two older boys showed cerebral atrophy by CT. No metabolic abnormalities were identified. Three obligate carriers had an IQ less than 80. The causal gene has been localized distal to DXS8103 in Xq28, a region spanning 5cM. No other XLMR disorder with these manifestations have been localized to this region and this appears to be a new disorder.- - - - - - - - - - ranking = 5keywords = hypertelorism (Clic here for more details about this article) |
7/389. Severe end of Opitz trigonocephaly (C) syndrome or new syndrome?We report on four unrelated cases of an Opitz trigonocephaly (C)-like syndrome with a highly characteristic combination of facial anomalies including prominent metopic suture, exophthalmos, hypertelorism, cleft lip and palate, flexion deformities of the upper limbs and multiple other anomalies. We also review two very similar published cases formerly considered to have the C syndrome. Although there is overlap, a clinical distinction from the Opitz trigonocephaly and other syndromes seems possible, and thus a specific causal entity may be postulated.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
8/389. A 100-year-old anatomical specimen presenting with boomerang-like skeletal dysplasia: diagnostic strategies and outcome.The Museum Vrolik collection of human anatomy comprises 360 recently redescribed specimens with congenital anomalies. The specimen described here dated from 1881 and presented with a general embryonic appearance, disproportionate short stature, brachycephaly, widened cranial sutures, hypertelorism, microphthalmia, bilateral cleft lip and palate, micrognathia, short and curved limbs, polysyndactyly, and abnormal female genitalia. Conventional radiography was hampered by decalcification of the skeleton, due to acidification of the preservation fluid. The use of additional imaging techniques, i.e., mammography, computerized tomography with three-dimensional reconstruction, and magnetic resonance imaging eventually led us to conclude that the condition of our specimen was similar to Piepkorn type skeletal dysplasia, boomerang dysplasia, and a condition described by Carpenter and Hunter [1982: J Med Genet 19:311-315], though none of these diagnoses seemed fully applicable.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
9/389. Ophthalmic features of chromosome deletion 4p- (wolf-hirschhorn syndrome).By using the Giemsa banding technique we identified three patients with chromosome deletion 4p-. All had anterior segment anomalies, exotropia, blepharoptosis, antimongoloid palpebral fissures, hypertelorism, and disk abnormalities. One patient (Case 1) had Rieger's anomaly. Some clinical features in patients with 4p- are similar to those in patients with chromosome deletion 5p-, cri-du-chat syndrome, although 4p- individuals do not have the distinctive cry. The ocular features which distinguish 4p- from other deletions include normal tearing, some degree of blepharoptosis, and the preponderance of anterior segment signs.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
10/389. Two sibs with Malpuech syndrome.We report on two Italian brothers with facial clefting, hypertelorism, urogenital anomalies including micropenis, shawl scrotum, hearing loss, caudal appendage, and umbilical hernia. We have evaluated the two cases as Malpuech syndrome. This is an extremely rare autosomal recessive syndrome.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
