1/24. 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 = craniofacial (Clic here for more details about this article) |
2/24. Autosomal recessive multiple pterygium syndrome: a new variant?Multiple pterygium syndromes include at least 15 different entities characterized by multiple pterygia or webs of the skin and multiple congenital anomalies. We describe a female infant who presented with a distinct constellation of multiple anomalies consisting of pterygia of the inguinal, intercrural and popliteal areas, flexion contractures and arthrogryposis of some joints, craniofacial anomalies including ectropion, medial canthal web, blepharophimosis, hypoplasia of nose, oral and nasopharyngeal cavities, vocal cords and tongue, micrognathia, orolabial synechiae secondary to pterygia, low set ears, alopecia, sad and expressionless face, short neck, asymmetric nipples, anal stenosis, rectal polyp, hypoplastic labia majora, complete syndactyly of all fingers and toes, pes equinovarus, bandlike web between feet, and absence of the nails and phalangeal-palmar creases. Radiological examination showed synostosis, absence or hypoplasia of metacarpal, metatarsal and phalangeal bones on feet and hands, and hypoplasia of pelvic bones and scapulae. This pattern of anomalies does not fit entirely any of the known multiple pterygium syndromes. Autosomal recessive inheritance is most likely due to the presence of three similarly affected siblings and normal parents.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
3/24. Fraser-cryptophthalmos syndrome.Fraser or Cryptophthalmos syndrome is a variable syndrome to the extent that cryptophthalmos might not be present in all cases. However, the main features are a "hidden eye", other craniofacial abnormalities, renal abnormalities, syndactyly and abnormal genitalia. It may be classified as isolated cryptophthalmos or cryptophthalmos sequence and cryptophthalmos syndrome. The cryptophthalmos syndrome has an autosomal recessive mode of inheritance. Isolated cryptophthalmos has been reported as an autosomal dominant trait. prenatal diagnosis is possible using ultrasonography and fetoscopy. We report three cases of cryptophthalmos. One with renal agenesis had cryptophthalmos syndrome and the other two had isolated cryptophthalmos or cryptophthalmos sequence.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
4/24. fraser syndrome with bladder pseudoexstrophy.We report a one year old girl with fraser syndrome (the association of craniofacial abnormalities, syndactaly and cryptophlamos) and multiple urogenital abnormalities including clitorimegaly, left renal agenesis and a unique urinary bladder exstrophy variant (psuedoexstrophy) with intact bladder which herniates through the lower abdominal wall defect.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
5/24. Trigonomicrocephaly, severe micrognathia, large ears, atrioventricular septal defect, symmetrical cutaneous syndactyly of hands and feet, and multiple cafe-au-lait spots: new acrocraniofacial dysostosis syndrome?We report on a patient with a unique constellation of anomalies comprising trigonomicrocephaly, asymmetric severe micrognathia, large ears, atrioventricular septal defect, vertebral anomalies, bilateral cutaneous syndactyly of fingers and toes, unilateral cryptorchidism and multiple cafe-au-lait spots. The mother of the propositus has multiple cafe-au-lait spots. Search of POSSUM and the london Dysmorphology database (LDDB) uncovered no similar case. We think that this patient represents a new acrocraniofacial dysostosis syndrome.- - - - - - - - - - ranking = 5keywords = craniofacial (Clic here for more details about this article) |
6/24. Analysis of the p63 gene in classical EEC syndrome, related syndromes, and non-syndromic orofacial clefts.EEC syndrome is an autosomal dominant disorder with the cardinal signs of ectrodactyly, ectodermal dysplasia, and orofacial clefts. EEC syndrome has been linked to chromosome 3q27 and heterozygous p63 mutations were detected in unrelated EEC families. In addition, homozygous p63 null mice exhibit craniofacial abnormalities, limb truncations, and absence of epidermal appendages, such as hair follicles and tooth primordia. In this study, we screened 39 syndromic patients, including four with EEC syndrome, five with syndromes closely related to EEC syndrome, and 30 with other syndromic orofacial clefts and/or limb anomalies. We identified heterozygous p63 mutations in three unrelated cases of EEC syndrome, two iowa white families and one sporadic case in a Filipino boy. One family is atypical for EEC and has features consistent with Hay-Wells syndrome. In this family, the mutation ablates a splice acceptor site and, in the other two, mutations produce amino acid substitutions, R280C and R304Q, which alter conserved dna binding sites. Germline mosaicism was detected in the founder of the mutation in one case. These three cases show significant interfamilial and intrafamilial variability in expressivity. We also screened p63 in 62 patients with non-syndromic orofacial clefts, identifying an intronic single nucleotide polymorphism but finding no evidence of mutations that would explain even a subset of non-syndromic orofacial clefts. This study supports a common role for p63 in classical EEC syndrome, both familial and sporadic, but not in other related or non-syndromic forms of orofacial clefts.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
7/24. Pierre Robin sequence in a patient with ectrodactyly-ectodermal dysplasia-clefting syndrome: a case report and review of the literature.Ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome is a rare condition first identified in 1970. The majority of cases are reported to be autosomal dominant with variable expression and penetrance. The most common clinical feature is ectodermal dysplasia. Ectrodactyly, cleft lip with or with out cleft palate and urogenital anomalies are also main clinical features of EEC syndrome. Pierre Robin (PR) sequence has the clinical findings of micro-retrognathia, retroposed tongue (glossoptosis), cleft of the secondary palate, and upper airway obstruction. Etiologically PR sequence is heterogeneous. It has been reported that less than 20% of cases are isolated, non-syndromic PR sequence. We present a case of a newborn male who was referred to our craniofacial clinic with EEC syndrome and PR sequence. This case represents a unique clinical association. We found no other reports in the literature of these two clinical entities occurring together. Upper airway obstruction of PR sequence, secondary to glossoptosis and micro-retrognathia, gives this association clinical relevance. In addition, this clinical association may represent a new gene locus associated with EEC syndrome.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
8/24. Short stature, sensorineural deafness, ocular abnormalities and severe mental retardation in two siblings. A new syndrome?We describe a brother and sister with craniofacial dysmorphism, short stature, relative obesity, sensorineural deafness, multiple pigmented naevi and severe mental retardation. One sibling had keratoconus and the other had an iris coloboma. Dysmorphic features included brachycephaly, hypotelorism, small mouth, thin lips, pterygium colli, broad chest, widely spaced nipples and cutaneous second and third toe syndactyly. The children demonstrate some features of noonan syndrome, but we believe that they have a different and distinctive phenotype. We have reviewed similar cases in the literature and discuss these in the context of our cases, who may have a previously undescribed syndrome.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
9/24. Combined chemotherapy and teratogenicity.BACKGROUND: The concomitant occurrence of breast cancer and pregnancy is relatively uncommon. We report the case of a patient with syndactyly, cleft hands, and absence of distal finger phalanges associated with maternal exposure to chemotherapeutic agents during the first trimester of pregnancy. These associations have not been previously described. CASE: The patient was born by normal delivery after 38 weeks of pregnancy. His mother became pregnant while receiving chemotherapy (cyclophosphamide, 5-fluorouracil, and adriamycin) for breast cancer, and the fetus was exposed to these drugs from conception to the 16th week of pregnancy. At birth, anomalies were observed, including a high-arched palate, microcephaly, a flat nasal bridge, bilateral syndactyly in the first and second fingers with a hand cleft between the second and third fingers and hypoplasia of the fifth fingers, and dystrophic nail of the fourth finger of the left hand. The patient's growth and development were deficient. CONCLUSIONS: The malformations associated with in utero exposure to these chemotherapeutic agents are highly variable, but growth deficiency and anomalies of the craniofacial region and limbs are the most common. The pattern of malformations in children who were congenitally exposed to chemotherapeutic agents appears to be directly related to the age at and duration of exposure, rather than to the specific drug itself. Effective contraception is essential for the safe use of a potential teratogen in nonpregnant women of reproductive age.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
10/24. Further delineation of the acrocallosal syndrome.The acrocallosal syndrome (ACS) was recognized by Schinzel in 1979 as a specific entity, characterized by the association of craniofacial anomalies, total or partial agenesis of corpus callosum, polysyndactyly and mental retardation. The inheritance is autosomal recessive, based on instances of recurrence in siblings and cousins and parental consanguinity. A large inbred kindred with recurrent ACS is presented. This family further strengthens the hypothesis of autosomal recessive inheritance for this syndrome. The array of clinical manifestations in this sibship and those previously reported exemplify the phenomenon of inter- and intrafamilial variability that must be considered when defining ACS. Based on a review of published reports and the present family, essential, additional and occasional findings are distinguished. attention is drawn to geographical clustering of the families.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
