1/4. Craniofacial-deafness-hand syndrome revisited.In 1983 Sommer described a new syndrome in a mother and her infant daughter which was subsequently called the syndrome of craniofacial, hand anomalies and sensorineural deafness. The syndrome consisted of a normal calvarium with a flat facial profile, hypertelorism and small palpebral fissures with an antimongoloid slant, a depressed nasal bridge with a button tip and slitlike nares and a small "pursed" mouth. Profound sensorineural hearing loss and ulnar deviation of the hands with flexion contractures of digits three, four and five was evident. The family had another child, a son, two years after the birth of the index case that had the exact manifestations as his mother and sister. Because of three affected family members in two generations and a phenotype of midfacial anomalies and dystopia canthorum resembling waardenburg syndrome, a search for mutations in the PAX3 gene was undertaken. A missense mutation in the paired domain of PAX3 (Asn47Lys) was detected. We have provided a 20-year follow-up of a syndrome characterized by craniofacial anomalies, hearing loss and hand deformities and which is caused by a PAX3 missense mutation.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
2/4. Popliteal pterygium syndrome with unusual features.Popliteal pterygium syndrome is a well defined complex that consists of popliteal pterygium, intercrural pterygium, various digital anomalies that include hypoplasia or agenesis of digits, syndactyly, valgus or varus deformities of the feet and oral anomalies such as cleft lip-palate. A baby with the typical anomalies as well as a few unusual features such as mongloid slant, hypertelorism, malformed alae nasi and elbow joint contractures is reported.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
3/4. Oto-palato-digital syndrome type II. Report of two related cases.Two cases with major features of bowed long bones, hypertelorism, mandibular hypoplasia and hand and foot abnormalities with early neonatal death due to respiratory failure are presented. The radiologic and clinical findings are in keeping with oto-palato-digital syndrome type II and differ significantly from other causes of bowed long bones such as campomelic and kyphomelic dysplasias.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
4/4. Examine your orofacial cleft patients for Gorlin-Goltz syndrome.The Gorlin-Goltz syndrome is characterized by four primary symptoms: multiple nevoid basal cell epitheliomas that usually undergo malignant transformation; jaw keratocysts that show constant growth; skeletal anomalies; and intracranial calcifications. A myriad of additional findings may also be noted. Among the most frequent are: palmar and plantar pits, a characteristic flattened facies and broad nasal root, frontal and parietal bossing, mandibular prognathia, hypertelorism, strabismus, dystrophia of the canthi, and clefts of the lip, alveolus, and/or palate. In this study, we review the literature and our 25 cases of Gorlin-Goltz syndrome patients, questioning their incidence of cleft formations (8.5%) as compared to the general population (0.1%). It is our contention that all patients who present with an orofacial cleft warrant deeper investigation as to the presence of additional signs indicative of Gorlin-Goltz syndrome. The nevi turn malignant with time, and thus, early diagnosis, follow-up, and treatment are imperative.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
