Abstract
INTRODUCTION Fraser syndrome, named after George Fraser, is an autosomal recessive disorder showing a highly variable interfamilial phenotypic variation, with malformations ranging from minor symptoms to lethal anomalies like renal agenesis, incompatible with survival. Limb reduction defects have not been reported to be associated with it. CASE PRESENTATION A 21-year-old primigravida presented to the antenatal outpatient department with a level two targeted anomaly scan report suggestive of severe oligohydramnios with suspected renal agenesis. The cranial vault bones were compressed, and orbital globes and lenses could not be visualized. Renal agenesis was confirmed due to sleeping adrenals sign, non-visualization of the urinary bladder, and Doppler of renal arteries. A detailed examination of the fetal head in the sagittal section showed the absence of an eye globe and lens, arousing suspicion of Fraser syndrome. After pregnancy termination, a complete fetal autopsy was done to look for any additional findings. CONCLUSION Patients who have a syndromic mix of acrofacial and urogenital abnormalities with or without cryptophthalmos should be evaluated for Fraser syndrome, which can be diagnosed by clinical examination and perinatal autopsy.

Abstract
Fraser syndrome (cryptophthalmos-syndactyly syndrome) is a rare autosomal recessive malformation disorder. The first description of the syndrome was reported by George Fraser in 1962. Diagnosis is based on the major and minor criteria established by van Haelst et al. in 2007. Unilateral or bilateral cryptophthalmos, syndactyly, unilateral renal agenesis, and genital anomalies are the most frequent anomalies. Several maxillofacial, oro-dental, ear-nose-throat, hormonal, and anorectal disorders are reported. Cardiac malformations and musculoskeletal anomalies are uncommon. The syndrome is related to mutations in three different genes (FRAS1, FREM2, and GRIP1) resulting in failure of the apoptosis program and disruption of the epithelial-mesenchymal interactions during embryonic development. Prenatal diagnosis is based on the detection of renal agenesis and laryngeal atresia, together with a family history. Most foetuses with severe anomalies are terminated or are stillborn. All patients or pregnancies with a diagnosis of Fraser syndrome should be referred to expert centres. A collaborative approach including anaesthetists, ENT specialists, maxillofacial surgeons, and geneticists is necessary for the management of this syndrome. In vivo and in vitro research models are available to better understand the underlying aetiology.

Abstract
Background Fraser syndrome is an autosomal recessive disorder characterized primarily by syndactyly, cryptophthalmos, urinary tract anomalies, ambiguous genitalia, and laryngeal anomalies. A 28-year-old man with Fraser syndrome presented with cryptophthalmos, microphthalmia, lacrimal system dysgenesis, and chronic sinusitis. Objective The patients’ clinical condition and surgical treatment are described. A literature review was conducted, and articles relevant to the case are presented. Methods Case report. Results To our knowledge, this is the first published case report of endonasal management of dacryocystoceles in a Fraser syndrome patient. The patient was treated via endoscopic endonasal marsupialization and drainage. Conclusion Fraser syndrome patients may initially present to many different specialties as the spectrum of clinical manifestations is broad. Physicians treating these patients should take a collaborative approach to surgical and medical management.

Abstract
OBJECTIVE Fraser syndrome (FS) is a rare malformation recessive disorder. Major criteria are cryptophtalmos, syndactyly, respiratory, genital and urinary tract anomalies. Few prenatal presentations have been reported. METHOD We analyzed the prenatal and postnatal fetal phenotype in 38 cases of FS, including 25 pregnancy termination cases, 8 intra-uterine death cases and 4 cases that died after birth. RESULTS Including both prenatal and postnatal fetal phenotypic evaluation, all cases presented dysmorphic features with nose and ear dysplasia. Renal anomalies and syndactyly were present in 37/38 cases, cryptophtalmos in 36/38, airways anomalies in 30/37 and genital anomalies in 30/35 cases. Anomalies of the abdominal wall such as low set umbilicus and omphalocele were found in 31 cases. Among the 26 cases for which ultrasound data were available, detectable anomalies included oligohydramnios (22), ascites/hydrops (9), renal anomalies (20), evidence for high airways obstruction (11), ophthalmologic anomalies (4), ear dysplasia (2) and syndactyly (2). CONCLUSION This study shows that the postnatal phenotype of FS is very specific, whereas oligohydramnios hampers the prenatal recognition of the cardinal FS diagnosis criteria. Association of oligohydramnios, kidney agenesis and CHAOS should lead to consider this diagnosis. © 2016 John Wiley & Sons, Ltd.

Abstract
Fraser syndrome is a rare genetic malformation with an autosomal recessive pattern of inheritance and an incidence of consanguinity ranging from 15% to 25%. A 5-year-old male patient who is a carrier of Fraser syndrome initiated treatment in the pediatric dentistry sector. The patient was fed parenterally since birth, experienced recurring bouts of chronic lung disease, and was referred to the pediatric dentistry sector by the medical team. Radiographic examination revealed the presence of all permanent teeth. Supragingival dental calculus, halitosis, and gingival inflammation were also observed. Dental calculus was removed by manual scraping, and chemotherapeutic agents were used, chlorhexidine 0,12%, chlorhexidine gel 2%, and PVP-I, to control the bacterial flora. The patient is still being monitored after an 8-year follow-up period, the complications associated with periodontal disease decreased, and since the initiation of treatment, the patient has not needed to be hospitalized because of chronic lung disease. This study reports the case of a patient diagnosed with Fraser syndrome and describes the clinical manifestations (general and oral).

Abstract
Fraser syndrome is a rare autosomal recessive disorder characterized by cryptophthalmos, cutaneous syndactyly, laryngeal, and urogenital malformations. We present a population-based epidemiological study using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network of birth defect registries. Between January 1990 and December 2008, we identified 26 cases of Fraser syndrome in the monitored population of 12,886,464 births (minimal estimated prevalence of 0.20 per 100,000 or 1:495,633 births). Most cases (18/26; 69%) were registered in the western part of Europe, where the mean prevalence is 1 in 230,695 births, compared to the prevalence 1 in 1,091,175 for the rest of Europe (P = 0.0003). Consanguinity was present in 7/26 (27%) families. Ten (38%) cases were liveborn, 14 (54%) pregnancies were terminated following prenatal detection of a serious anomaly, and 2 (8%) were stillborn. Eye anomalies were found in 20/24 (83%), syndactyly in 14/24 (58%), and laryngeal anomalies in 5/24 (21%) patients. Ambiguous genitalia were observed in 3/24 (13%) cases. Bilateral renal agenesis was present in 12/24 (50%) and unilateral in 4/24 (17%) cases. The frequency of anorectal anomalies was particularly high (42%). Most cases of Fraser syndrome (85%) are suspected prenatally, often due to the presence of the association of renal agenesis and cryptophthalmos. In the European population, a high proportion (82%) of pregnancies is terminated, thus reducing the live birth prevalence to a third of the total prevalence rate.

Abstract
QBRICK facilitates the integrin α8β1–dependent interactions of cells with basement membranes by regulating the basement membrane assembly of nephronectin. Dysfunction of the basement membrane protein QBRICK provokes Fraser syndrome, which results in renal dysmorphogenesis, cryptophthalmos, syndactyly, and dystrophic epidermolysis bullosa through unknown mechanisms. Here, we show that integrin α8β1 binding to basement membranes was significantly impaired in Qbrick-null mice. This impaired integrin α8β1 binding was not a direct consequence of the loss of QBRICK, which itself is a ligand of integrin α8β1, because knock-in mice with a mutation in the integrin-binding site of QBRICK developed normally and do not exhibit any defects in integrin α8β1 binding. Instead, the loss of QBRICK significantly diminished the expression of nephronectin, an integrin α8β1 ligand necessary for renal development. In vivo, nephronectin associated with QBRICK and localized at the sublamina densa region, where QBRICK was also located. Collectively, these findings indicate that QBRICK facilitates the integrin α8β1–dependent interactions of cells with basement membranes by regulating the basement membrane assembly of nephronectin and explain why renal defects occur in Fraser syndrome.

Abstract
Fraser syndrome is an autosomal recessive congenital malformation syndrome characterized by cryptophthalmos, syndactyly, and urogenital defects. We studied the clinical features in 59 affected individuals from 40 families (25 consanguineous), and compared our findings to data from previous reviews. We found a higher frequency of abnormalities of the skull, larynx, umbilicus, urinary tract, and anus in our series of patients, and mental retardation and cleft lip with or without cleft palate were observed less frequently than previously reported. Clinical features in probands and sibs were remarkably similar. As can be expected prenatally diagnosed patients had more manifestations that gave rise to a pathological amount of amniotic fluid. Otherwise patients diagnosed before and after birth had similar frequencies of symptoms. Based on the present results we suggest an adaptation of diagnostic criteria for FS, including adding airway tract and urinary tract anomalies as major criteria. The specificity of the proposed diagnostic criteria was evaluated using the London Medical Database as a search tool.

Abstract
To date, Fraser syndrome (FS) and Ablepharon macrostomia syndrome (AMS) have been considered distinct disorders, but they share strikingly similar patterns of congenital abnormalities, specifically craniofacial anomalies. While recent research has led to the identification of the genes FRAS1 and FREM2 as the cause of FS, the genetic basis of AMS continues to be enigmatic. We report on the concurrence of AMS-like and Fraser phenotypes in a Brazilian family. Both affected sibs were homozygous for a novel splice site mutation in the FRAS1 gene. Extensive studies on mRNA expression indicated that this mutation most likely leads to loss of function as most previously reported FRAS1 mutations associated with FS. We conclude that a phenotype resembling AMS is a rare clinical expression of FS with no obvious genotype-phenotype correlation. However, the molecular basis of "true" AMS which has been reported as a sporadic disorder in all cases but one, and so far with no relation to FS, is probably different and still needs to be further investigated.

Abstract
Fraser syndrome (OMIM 219000) is a rare, autosomal recessive disorder characterized by cryptophthalmos, cutanaeous syndactyly, malformations of the larynx and genitourinary tract, craniofacial dysmorphism, orofacial clefting, mental retardation and musculoskeletal anomalies. There is marked interfamilial clinical heterogeneity. However, there is strong phenotypic similarity and concordance of the degree of severity of the disease within a family. We report a family with two cases of Fraser syndrome with marked clinical heterogeneity. One case had lethal phenotype with bilateral renal agenesis, while the other had mild phenotype with normal kidneys. It has not been reported before and highlights the importance of careful screening of pregnancies in families with Fraser syndrome.

Abstract
An emerging family of extracellular matrix proteins characterized by 12 consecutive CSPG repeats and the presence of Calx-beta motif(s) includes Fras1, QBRICK/Frem1, and Frem2. Mutations in the genes encoding these proteins have been associated with mouse models of Fraser syndrome, which is characterized by subepidermal blistering, cryptophthalmos, syndactyly, and renal dysmorphogenesis. Here, we report that all of these proteins are localized to the basement membrane, and that their basement membrane localization is simultaneously impaired in Fraser syndrome model mice. In Frem2 mutant mice, not only Frem2 but Fras1 and QBRICK/Frem1 were depleted from the basement membrane zone. This coordinated reduction in basement membrane deposition was also observed in another Fraser syndrome model mouse, in which GRIP1, a Fras1- and Frem2-interacting adaptor protein, is primarily affected. Targeted disruption of Qbrick/Frem1 also resulted in diminished expression of Fras1 and Frem2 at the epidermal basement membrane, confirming the reciprocal stabilization of QBRICK/Frem1, Fras1, and Frem2 in this location. When expressed and secreted by transfected cells, these proteins formed a ternary complex, raising the possibility that their reciprocal stabilization at the basement membrane is due to complex formation. Given the close association of Fraser syndrome phenotypes with defective epidermal-dermal interactions, the coordinated assembly of three Fraser syndrome-associated proteins at the basement membrane appears to be instrumental in epidermal-dermal interactions during morphogenetic processes.

Abstract
Fraser syndrome is a recessive multisystem disorder characterized by embryonic epidermal blistering, cryptophthalmos, syndactyly, renal defects and a range of other developmental abnormalities. More than 17 years ago, the family of four mapped mouse blebs mutants was proposed as models of this disorder, given their striking phenotypic overlaps. In the last few years, these loci have been cloned, uncovering a family of three large extracellular matrix proteins and an intracellular adapter protein which are required for normal epidermal adhesion early in development. The proteins have also been shown to play a crucial role in the development and homeostasis of the kidney. We review the cloning and characterization of these genes and explore the consequences of their loss.

Abstract
Fraser syndrome (OMIM 219000) is a rare, autosomal recessive condition with classical features of cryptophthalmos, syndactyly, ambiguous genitalia, laryngeal, and genitourinary malformations, oral clefting and mental retardation. Mutations causing loss of function of the FRAS1 gene have been demonstrated in five patients with Fraser syndrome. However, no phenotype-genotype correlation was established and there was evidence for genetic heterogeneity. Fraser syndrome is rare and the FRAS1 gene has 75 exons, complicating mutation screening in affected patients. We have screened two patients who fulfilled the diagnostic criteria for Fraser syndrome and three patients with related phenotypes (two patients with Manitoba oculotrichoanal syndrome and one patient with unilateral cryptophthalmos and labial fusion) for mutations in FRAS1 to increase the molecular genetic data in patients with Fraser syndrome and related conditions. We report two new mutations in a patient with Fraser syndrome, a frameshift mutation and a deletion of two amino acids that we consider pathogenic as both alter the NG2-like domain of the protein. Although we are still unable to clarify a phenotype-genotype relationship in Fraser syndrome, our data add to the list of mutations associated with this syndrome.

Abstract
Cryptophthalmos may be partial or complete, unilateral or bilateral, apparently nonsyndromal or syndromal. A recent study of 2 stillborn infants at the University of Utah prompted an analysis of the developmental aspects of the syndromal form (Fraser syndrome). We conclude that, per se, cryptophthalmos is a developmental field defect on the basis of heterogeneity (autosomal dominant and recessive forms) and phylogeneity (occurrence also in the pheasant, rabbit, pigeon, dog, and mouse). In humans this autosomal recessive disorder maps to 4q21, is homologous to the bleb (bl/bl) mouse, and is due to mutations in the FRAS1 gene that codes for a 4007 amino acid protein 85% identical to the Fras1 gene of the bleb mouse. Commonest anomalies in humans are cryptophthalmos, cutaneous syndactyly of digits, abnormal ears and genitalia, renal agenesis, and congenital heart defects. Almost half of affected infants are stillborn or die in infancy, and mental retardation is common. The pathogenesis evidently involves abnormal epithelial integrity during prenatal life. Older (mostly German) publications, some dating to the 19th century, provide a fascinating historical insight into the process of syndrome delineation.

Abstract
OBJECTIVE To determine the possible association between congenital eye anomaly of a previous child in the family and current congenital eye anomaly. METHODS An early transvaginal anomaly scan at 14-16 gestational weeks was used to diagnose fetal eye anomalies in five cases in which at least one previous child in the family had the same congenital eye anomaly. RESULTS At least one cataract was detected in four of the five fetuses and bilateral anophthalmia in one. The congenital cataract in one case was part of multiple pterygium syndrome. Both of these extremely rare malformations are commonly associated with other fetal anomalies. CONCLUSION Our data suggest that a detailed targeted ultrasound survey with a special focus on the orbital region should be offered at the time of genetic counseling to couples with children with congenital eye anomalies.

Abstract
Fraser syndrome is characterised by cryptophthalmos, cutaneous syndactyly, malformations of the larynx and genitourinary tract, craniofacial dysmorphism, orofacial clefting, mental retardation, and musculoskeletal anomalies. The inheritance is autosomal recessive. No diagnostic cytogenetic abnormalities have been documented in affected patients, and no molecular genetic studies have been reported. We have reviewed 117 cases diagnosed as Fraser syndrome or cryptophthalmos published since the comprehensive review of Thomas et al in 1986 in order to validate the published diagnostic criteria and to delineate the phenotype associated with this syndrome. Our series showed more females (57/117) than males and consanguinity was present in 29/119 (24.8%). Eighty-eight patients satisfied the diagnostic criteria for Fraser syndrome (75%). Cryptophthalmos was present in 103/117 (88%), syndactyly in 72/117 (61.5%), and ambiguous genitalia in 20/117 (17.1%). Ear malformations were recorded in 69/117 (59%), and renal agenesis in 53/117 (45.3%). Use of the published diagnostic criteria excluded several patients with cryptophthalmos and one or more physical feature(s) consistent with Fraser syndrome. The frequency of additional anomalies in our series was also higher than previously reported (for example, imperforate anus or anal stenosis were found in 34/117 (29%) compared with 2/124 (2%) in the series of Thomas et al (1986) and choanal stenosis or atresia was present in 7/117 (6%) compared to 0/124. These findings emphasise the clinical variability associated with Fraser syndrome and support genetic heterogeneity of the syndrome. We also noted patterns of anomalies (for example, bicornuate uterus with imperforate anus or anal stenosis and renal malformations) that are found in other syndromes and associations without cryptophthalmos, suggesting that common modifier genes may explain some of the phenotypic variation in Fraser syndrome.

Abstract
Fraser syndrome (MIM 219000) is a rare disorder of autosomal recessive inheritance, characterized by the association of cryptophthalmos, syndactyly and genital abnormalities. Here we report on two cases of Fraser syndrome (cryptophthalmos syndrome) in a non-consanguineous couple, with variable expression in echographic, clinical and autopsy findings. Furthermore, we highlight the difficulties in prenatal diagnosis of Fraser syndrome.

Abstract
Renal abnormalities are some of the commonest and most easily detectable anomalies on ultrasound. Many are an isolated finding but the prognosis may be altered considerably by the detection of other anomalies which could indicate a genetic disorder or syndrome. It is often easier to detect presupposed anomalies and the purpose of this article is to introduce and discuss those syndromes that may present with a renal abnormality on ultrasound. Common renal findings are presented with the range of additional anomalies that should be sought and suggested diagnostic tests. It should be remembered that although for many genetic conditions specific mutation analysis is now available, this usually requires pre-pregnancy investigations. Furthermore, in some cases the definitive diagnosis may not be suspected until post mortem. By this time it may be too late to establish a cell line to confirm the suspicion using laboratory methods. It is therefore important to take tissue samples antenatally where possible, or at delivery, as postnatal samples may have a high culture failure rate.

Abstract
Fraser syndrome (cryptophthalmos-syndactyly syndrome) is an autosomal recessive multiple malformation syndrome whose major manifestations are cryptophthalmos, syndactyly, laryngeal atresia and urogenital defects. Enlarged hyperechogenic lungs contrasted by oligohydramnios, non-visualization of the kidneys and microphthalmia were sonographic markers leading to the prenatal detection of this rare autosomal recessive disorder in earlier reports. We report a case of Fraser syndrome diagnosed at 16 weeks' gestational age in a woman whose previous pregnancy was terminated because of multiple fetal malformations. Abnormal sonographic findings included bilateral agenesis of the kidneys, dilated trachea and main bronchi (suggestive of high airway obstruction), hyperechogenic lungs, syndactyly of the fingers, hepatomegaly, oligohydramnios and hydrops placentae. Face and cerebral structures appeared normal. These findings together with those of the previously affected child led to the diagnosis of Fraser syndrome. The parents elected to terminate the pregnancy. Autopsy results were confirmatory. In conclusion, prenatal diagnosis of Fraser syndrome is possible in the hands of an expert, but due to the great variety of possible malformations the diagnosis will remain doubtful in most cases in which no previous child is affected.

Abstract
We report on an 8-year-old Thai girl with bilateral complete cryptophthalmos, facial asymmetry, delayed bone age, brachymesophalangy and medial deviation of the second toes, and dental anomalies. The dental anomalies consist of delayed dental development, congenital absence of the second premolars, microdontia of the deciduous molars. A fibrous band of the buccal mucosa was found. Dental anomalies are rare among patients with Fraser syndrome. They have not been reported in either isolated or other syndromic cryptophthalmos. The oral manifestations and brachymesophalangy of the second toes found in our patient may represent newly recognized findings associated with cryptophthalmos or they may represent a newly recognized syndrome.

Abstract
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.

Abstract
We describe a 25-week-old female fetus of consanguineous parents with ultrasonographic findings of increased echogenicity of lungs mimicking CAM (cystic adenomatoid malformation) type III, olygohydramnios and fetal ascites. A therapeutic abortion was performed and unilateral cryptophthalmos, laryngeal atresia and bilateral syndactyly of the hands and feet were observed at post-mortem. These findings confirmed the diagnosis of Fraser syndrome after abortion.

Abstract
We report two male siblings with cryptophthalmos syndrome (Fraser syndrome), an autosomal recessive multiple malformation syndrome with cryptophthalmos, abnormal genitalia, and syndactyly of the fingers and toes as major clinical symptoms. Renal anomalies (uni- or bilateral agenesis) occur in 85 per cent. In the second trimester of both pregnancies (at 23.5 and 18.5 weeks, respectively), echographic examination revealed multiple anomalies: oligoamnios sequence and fetal hydrops with nuchal oedema. Contrasting with the oligohydramnios, the lungs were voluminous and hyperechogenic. Fetopathological examination revealed that the oligoamnios sequence was due to major renal abnormalities (bilateral renal agenesis in the first, and unilateral renal agenesis and contralateral multicystic renal dysplasia in the second sibling). Laryngeal substenosis had resulted in another malformation sequence consisting of overdistended lungs, and non-immune fetal hydrops. The present experience shows that in the presence of an oligoamnios sequence with contrastingly voluminous, hyperechogenic lungs, the diagnosis of cryptophthalmos syndrome should seriously be considered in the differential diagnosis.

Abstract
In a consanguineous marriage, a woman at 32 weeks' pregnancy presented with intrauterine growth retardation and bilateral renal agenesis. Fraser syndrome (cryptophthalmus syndactyly syndrome) was diagnosed based on cryptophthalmos, atresia of meatus acusticus externus in auricula, syndactyly, hypoplastic larynx, hypoplastic left lung, agenesis of urinary system and aberrant pancreas in duodenum. The syndrome is inherited as a recessive trait and the risk of recurrence is 25%.

Abstract
Fraser syndrome is a rare autosomal recessive disorder whose major manifestations are cryptophthalmos, syndactyly and genital abnormalities. These patients also frequently have malformations of the ears, nose and/or larynx. The diagnosis is usually made at birth from the obvious malformations, although occasionally made on prenatal ultrasound. Treatment is dependent on which malformations are present and genetic counseling is indicated. Prognosis is dependent on the severity of renal and laryngeal malformations.

Abstract
PURPOSE This paper describes the surgical rehabilitation of a child with craniofacial anomalies, unilateral syndactyly, and partial unilateral cryptophthalmos associated with inferior colobomata of the iris and optic nerve and agenesis of the inferior rectus and inferior oblique muscles. The clinical presentation of cryptophthalmos is described. METHODS The medical literature since the original description of cryptophthalmos in 1872 was reviewed to define patterns of inheritance and the incidence of associated anomalies. RESULTS Including this patient, 149 case reports of cryptophthalmos were identified. In two families transmission from parent to child suggests dominant inheritance. None of the five dominant cases had any other anomalies, and all had bilateral complete cryptophthalmos. The incidence of cryptophthalmos in the remaining families is consistent with autosomal recessive inheritance. This group includes patients with bilateral, unilateral, and partial cryptophthalmos. Other anomalies are common, including those of the ear and nose, limbs, genitourinary system, and mouth and palate. Mortality in the perinatal period is associated with renal agenesis, laryngeal atresia, and pulmonary hypoplasia. CONCLUSIONS Cryptophthalmos is a rare congenital anomaly with two patterns of inheritance.

Abstract
We report on 2 sibs with the Fraser cryptophthalmos syndrome who had pulmonary hyperplasia and laryngeal stenosis. A third unrelated patient with Fraser syndrome had laryngeal stenosis, renal agenesis, and normal lung development, rather than the expected pulmonary hypoplasia. Three additional cases of pulmonary hyperplasia in the Fraser syndrome were ascertained from a review. In all of these cases the likely mechanism for pulmonary hyperplasia is retention of fetal lung fluid by laryngeal or tracheal obstruction.

Abstract
We report on 6 (3 male, 3 female) Manitoba Indian children with hypertelorism and variable combinations of unilateral eye malformations, aberrant anterolateral scalp hairline, and nasal and anal anomalies. These children belong to 4 related families. The parents and 7 other sibs are clinically unaffected. The family histories are otherwise unremarkable. The presence of 2 major malformations in sibs and related individuals (with unaffected parents) suggests that this is a newly described pleiotropic autosomal recessive syndrome. The differential diagnosis includes cryptophthalmos syndrome and several other related malformation syndromes. Although multifactorial determination cannot be excluded, the inbred, isolated population and distribution make autosomal recessive inheritance more likely.

Abstract
Sonography permitted the diagnosis of Fraser syndrome (cryptophthalmos-syndactyly syndrome) at 18.5 weeks of gestation in a fetus whose parents had had a previous affected child. The karyotype of that child was 46,XX,inv(9)(p11q21); the karyotype of the phenotypically normal father and of the fetus was 46,XY,inv(9)(p11q21). Findings on sonography included oligohydramnios with nonvisualization of kidneys, hypertelorism and microphthalmia, and markedly enlarged lungs. On autopsy at 19 weeks, findings included renal agenesis, cryptophthalmos with multiple abnormalities of the eyes and ocular adnexa, laryngeal atresia, pulmonary hyperplasia with accelerated maturation, absence of the Eustachian tube with connective tissue occupying the tympanic cavity and bone occluding the external acoustic meatus, and soft-tissue webbing between the digits. This is the second reported instance of prenatal diagnosis of Fraser syndrome in the second trimester. The histopathologic findings in Fraser syndrome at this gestational age, in particular the eye and ear, have not been described previously.

Abstract
We report on 3 sisters with a syndrome of unilobed or absent thymus, renal and ureter agenesis/dysgenesis, and intrauterine growth retardation (IUGR). Two of the 3 infants had a unilobed lung and imperforate anus. Recurrence was detected prenatally by the presence of progressive oligohydramnios and IUGR, a unilateral echogenic cystic mass in the renal fossa, and low amniotic fluid disaccharidases in association with an imperforate anus. Several genetic mechanisms can be invoked to explain this occurrence including autosomal recessive inheritance and an unrecognized chromosome imbalance.

Abstract
Clinical and autopsy findings in two fetuses and one newborn infant with Fraser syndrome are presented. Discussion focuses on the range of phenotypic expression within this autosomal-recessive disorder, the resulting difficulties in prenatal and postnatal diagnosis, and on the concept of a neurocristopathy as underlying disturbance.

Abstract
Babies with major malformations were identified during the Jamaica Perinatal Morbidity and Mortality Survey. They were found in 96 (8.6%) of 1112 perinatal and neonatal deaths coming to necropsy and in 28 (2.6%) of 1085 no so examined. The central nervous system was most commonly affected, followed by the renal, gastrointestinal, and cardiovascular systems in decreasing order of frequency. Many infants had abnormalities in more than one system and 10 malformation syndromes/sequences were identified. Although at the present time, major malformations make only a small contribution to perinatal and neonatal mortality in Jamaica, their importance will increase when deaths from other causes, such as birth asphyxia, decline. The type of malformation currently fatal in a particular population is relevant when planning diagnostic and surgical services for neonates and infants. It is also important to any discussions about provision of prenatal diagnostic services.
