1/9. 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) |
2/9. prenatal diagnosis of double autosomal mosaicism (47,XX, 8/47,XX, 14): phenotype and molecular cytogenetic analysis on different tissues.A female fetus with multiple congenital anomalies was found to have double autosomal mosaicism, 47,XX, 8/ 47,XX, 14 on chromosome analysis via amniocentesis. At delivery, the proband displayed dysmorphic features of hypertelorism, micrognathia, low set ears, cleft palate, clubfeet, omphalocele, absent gallbladder and congenital heart defects. fluorescence in situ hybridization demonstrated a marked discrepancy in cell line populations in the tissues examined.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
3/9. Donnai-Barrow syndrome: four additional patients.In 1993, Donnai and Barrow reported a new syndrome in two sets of sibs and in an unrelated child, including diaphragmatic hernia, exomphalos, absent corpus callosum, hypertelorism, myopia, and sensorineural deafness. Since then, only four similar patients have been documented. We describe four additional patients, including two sibling pairs from healthy parents. This report firmly establishes this syndrome as a distinct clinical entity and provides further evidence for its previously postulated autosomal recessive inheritance.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
4/9. 49, XXXXY syndrome.49, XXXXY syndrome is a rare sex chromosomal disorder. A 5-month-old boy had failure to thrive and multiple congenital anomalies including microcephaly, facial dysmorphism (hypertelorism, megacornea, cleft palate, and micrognathia), obvious heart murmur, umbilical hernia, microphallus, and mild clenched hands. Chromosomal studies via techniques of G-banding and fluorescence in situ hybridization showed the constitution to be 47, XXXXY in all cells. Ventriculomegaly and congenital cardiac defects (patent ductus arteriosus, atrial septal defect, and peripheral pulmonary stenosis) were noted. He has severe atopic dermatitis with high IgE levels and psychomotor retardation. After heart surgery and nutritional support, he has better growth and the rehabilitation program is continuing.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
5/9. Omphalocele and partial trisomy 1q syndrome.A male infant with partial trisomy 1q syndrome (46,XY,der(21),t(1;21)(q25;q22)pat) is described. Clinical findings include small for gestational age, hypoglycemia, ocular hypertelorism, microphthalmia, coloboma of the iris, low-set ears, beak nose, micrognathia, micropenis, cryptorchidism, presacral dimple, flexion contractures of the fingers, bifid thumb, Simian crease, and overriding toes. In addition, he had a large omphalocele not previously seen in trisomy 1q. Postmortem findings include underdeveloped cerebellum, a thymus with moderate depletion of thymocytes, a large PDA, ASD, small adrenal, and fatty change of the liver. The grandfather, father, and a male sibling have translocation t(1;21)(q25;q22). A family history of repeated spontaneous abortions is present.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
6/9. OEIS complex with craniofacial anomalies--defect of blastogenesis?We report on a 31-week fetus with hydrocephalus, hypertelorism, microtia, short neck, vertebral and rib defects, scoliosis, omphalocele, exstrophy of bladder, absent external genitalia and pubic rami, imperforate anus, diaphragmatic hernia, defective lobulation of lungs, single kidney, bicornuate uterus, and flexion deformities of the limbs. Similar extensive anomalies in the rostral and caudal regions were described by Russell et al. [pediatrics, 67:176-182, 1981] and Stewart et al. [Am J Med Genet, 45:426-429, 1993]. The patients described by them had a combination of the oculo-auriculo-vertebral sequence (OAV) and caudal deficiency sequence, whereas the patient reported here can best be described as a combination of OAV and OEIS (omphalocele, exstrophy of bladder, imperforate anus, spinal defects) complexes. The widespread malformations seen in our patient may be the result of an error during blastogenesis.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
7/9. Diaphragmatic hernia, exomphalos, absent corpus callosum, hypertelorism, myopia, and sensorineural deafness: a newly recognized autosomal recessive disorder?We describe unrelated male and female patients with an identical syndrome of diaphragmatic hernia, exomphalos, hypertelorism, agenesis of the corpus callosum, severe sensorineural deafness, and severe myopia. One child had an iris coloboma. After the birth of the first affected child in each family subsequent pregnancies were monitored with ultrasound scan and a further affected fetus was identified in both families. We conclude that this constellation of anomalies represents a distinct, previously unreported syndrome with likely autosomal recessive inheritance.- - - - - - - - - - ranking = 5keywords = hypertelorism (Clic here for more details about this article) |
8/9. Diaphragmatic hernia-exomphalos-hypertelorism syndrome: a new case and further evidence of autosomal recessive inheritance.We describe a male patient with wide anterior fontanel and metopic suture, hypertelorism, down slanting palpebral fissures, bilateral iris coloboma, omphalocele, and bilateral absence of the diaphragm with herniation of abdominal organs causing pulmonary hypoplasia and death. autopsy also showed intestinal malrotation. All findings in this case are consistent with those described as a newly recognized syndrome by Donnai and Barrow [1993]. Since the parents are first cousins, this case provides further evidence for the previously postulated autosomal recessive inheritance pattern. Follow-up on the patients and families reported by Donnai and Barrow [1993] also supports autosomal recessive inheritance.- - - - - - - - - - ranking = 5keywords = hypertelorism (Clic here for more details about this article) |
9/9. Further clinical delineation and increased morbidity in males with osteopathia striata with cranial sclerosis: an X-linked disorder?Osteopathia striata with cranial sclerosis (OS-CS) is a bone dysplasia characterized by hypertelorism, macrocephaly, frontal bossing, broad nasal bridge, palate anomalies, hearing deficits, and mental retardation. The radiographic findings include cranial sclerosis, linear striations in the long bones and iliac wings, small poorly aerated sinuses, scoliosis, and increased bone density. The sensory deficits are disabling, but the condition generally is not life threatening. We describe 4 brothers with the characteristics of OS-CS, 3 of whom have died from more serious complications of the disorder. The mother of these children, and her only daughter, have the mildest phenotype with the typical linear striations in the long bones and macrocephaly. OS-CS is thought to be autosomal dominant with complete penetrance and variable expressivity. Our observations could be consistent with X-linkage, since there is milder expression in the female relatives. In addition, we recognize absent fibulae, malrotation, and omphalocele as new manifestations as well as congenital heart disease.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
