Abstract
Hirschsprung disease is a developmental disorder resulting from the arrest of the craniocaudal migration of enteric neurons from the neural crest along gastrointestinal segments of variable length; see Behrman [Nelson textbook of pediatrics, 1992:954-956]. It is a heterogeneous disorder in which familial cases map to at least three loci whose function is necessary for normal neural crest-derived cell development. Homozygous mutations in the endothelin-B receptor gene (EDNRB) on 13q22 have been identified in humans and mice with Hirschsprung disease type 2 (HSCR2). The auditory pigmentary disorder, Waardenburg-Shah syndrome, comprises Waardenburg syndrome and Hirschsprung disease and has also been mapped to the EDNRB locus. Hirschsprung disease, malrotation, isochromia, a profound sensorineural hearing loss, and several other anomalies were found in an infant with an interstitial deletion of 13q, suggesting the existence of a contiguous gene syndrome involving developmental genes necessary for the normal growth of the neural crest derivatives of the eye, inner ear, and colon. We report on an additional patient with a deletion in 13q and Hirschsprung disease. Congenital anomalies associated with deletions of the distal long arm of chromosome 13 are sufficiently consistent to suggest a clinical syndrome.

Abstract
We describe an apparently unique disorder, Fronto-Ocular syndrome, present in a mother and her two daughters, and comprising trigonocephaly due to coronal and metopic craniosynostosis, ocular hypotelorism, ocular proptosis and ptosis, epicanthal folds, hypoplastic supraorbital ridges, elevated nasal bridge, thin philtrum, high-arched palate and a narrow bifrontal region. Both daughters have glabellar capillary hemangiomas, a congenital heart defect and mild developmental disabilities. Review of the literature failed to disclose any syndrome with similar findings. It is likely that this disorder represents an autosomal dominant condition, that arose as a new mutation in the mother. Mutational analysis of fibroblast growth factor receptor (FGFR) 1 and FGFR2 failed to identify the molecular basis of the disorder.

Abstract
Apert syndrome, an autosomal dominant disorder characterized by craniosynostosis, mid-facial malformations, symmetric bony syndactyly of hands and feet, and varying degrees of mental retardation, is most frequently caused by a de novo mutation. Two missense mutations in the fibroblast growth factor receptor 2 (FGFR2) gene have been found to account for the disorder in approximately 98% of affected patients. Seven cases of prenatal ultrasound diagnosis have been reported. Although one earlier diagnosis has been made in a familial case, sporadic cases have not been definitively diagnosed until the third trimester when craniosynostosis is usually detected. We report a second-trimester molecular diagnosis of a sporadic case, based on the ultrasound observation of fetal 'mitten hands' and craniosynostosis. We discuss the approach to such ultrasound features, given the current availability of molecular diagnosis for Apert syndrome.

Abstract
Ring chromosomes are estimated to occur in 3/10000 newborns and the simultaneous occurrence of two autosomal rings must be a very rare event. Recently, the characterisation of these markers using fluorescence in situ hybridisation (FISH) has greatly enhanced cytogenetic-phenotypic correlations in patients with these marker chromosomes. This kind of analysis enabled us to clarify a unique karyotype containing a r(1) and a r(16) in identical twins born after a 26 week gestation with minimal somatic abnormalities. The origin of the rings was identified using a satellite and whole chromosome painting probes. FISH analysis showed the same abnormal female karyotype in both twins, 48,XX,+r(1)(p13q21),+r(16)(p11q11).ish r(1) (D1Z5+,wcpl+), r(16)(D16Z2+,wcp16+) in about two thirds of the cells. Each also had minor clones with a normal female karyotype or with one or the other supernumerary ring. Half of the r(1) contained CBG band negative material and the r(16) appeared to be totally CBG band positive. These twins represent the second report of the simultaneous occurrence of multiple autosomal rings. Their description may help to delineate a new chromosome disorder and shows the usefulness of FISH analysis.

Abstract
Glycogen storage disease type II (GSDII) is an autosomal recessive disorder resulting from inherited deficiency of the enzyme lysosomal acid alpha-glucosidase. Over 40 different mutations have been described but no large deletions have been previously identified. We now describe a homozygous large (9-kb) deletion extending from IVS 15 to 4 kb downstream of the terminal exon (exon 20), detected by polymerase chain reaction (PCR)-based methods. The deletion was initially suspected because of failure to amplify a contiguous group of exons by PCR. We hypothesized an Alu/Alu recombination, based on our prior demonstration by Southern blotting of Alu elements in the regions potentially flanking the deletion. Additional sequence analysis of genomic fragments confirmed the presence of Alu elements and allowed the design of flanking primers for PCR amplification. Amplification resulted in a smaller than normal fragment (0.7 vs. 10 kb) in homozygosity in the proband and in heterozygosity in her parents. Cloning and sequencing of the smaller than normal 0.7-kb deletion fragment revealed an Alu/Alu deletion junction. In heterozygosity this deletion would not be detected by currently standard PCR mutation detection methods. Based on other Alu-mediated deletions, this deletion is likely to be recurrent and should be screened for in all non-consanguineous GSDII patients, particularly when only one mutation has been identified and none of the 12 single-nucleotide polymorphisms in the deleted region are heterozygous. These observations also suggest that initial characterization of genes at disease-causing loci should include a search for Alu and other repetitive elements to facilitate subsequent PCR-based mutation analysis.

Abstract
The combination of complex congenital heart disease (double outlet right ventricle with pulmonary atresia, malalignment ventriculoseptal defect, right-sided aortic arch with left ductus arteriosus) and bladder exstrophy occurred in an infant with Opitz syndrome. Neither of these defects has previously been reported in association with Opitz syndrome. These malformations, which are midline defects, further characterize this syndrome as an impairment in midline development. The spectrum of congenital heart disease and genitourinary anomalies seen in Opitz syndrome is reviewed.

Abstract
Pfeiffer syndrome (PS) is an autosomal dominant condition comprising bilateral coronal craniosynostosis, midface hypoplasia with a beaked nasal tip, and broad and medially deviated thumbs and great toes. It is a clinically variable disorder and has been divided into three subtypes [Cohen, 1993: Am J Med Genet 45:300-307]. Type 1 represents the less severe cases, while types 2 and 3 are the more severe cases. These latter types tend to have a higher risk for neurodevelopmental problems and a reduced life expectancy. Here we review the clinical course of seven children with PS type 3. All of these children had severe manifestations of PS; however, development was essentially normal in three, mild delay was noted in two, and moderate delay in one. Favorable outcomes in children with types 2 and 3 PS were also documented by Moore et al. [1995: Cleft Pal-Craniofac J 32:62-70]. These cases illustrate that while children with PS types 2 and 3 have an increased risk for neurodevelopmental difficulties, a favorable outcome can be achieved in some cases with aggressive medical and surgical management. Finally, although such management should be the rule for PS types 2 and 3, it needs to be remembered that normal outcome is not the rule. The prognosis for favorable neurodevelopmental outcome and/or life expectancy remains guarded in most cases.

Abstract
Opitz syndrome (OS) is an inherited disorder characterized by midline defects including hypertelorism, hypospadias, lip-palate-laryngotracheal clefts and imperforate anus. We have identified a new gene on Xp22, MID1 (Midline 1), which is disrupted in an OS patient carrying an X-chromosome inversion and is also mutated in several OS families. MID1 encodes a member of the B-box family of proteins, which contain protein-protein interaction domains, including a RING finger, and are implicated in fundamental processes such as body axis patterning and control of cell proliferation. The association of MID1 with OS suggests an important role for this gene in midline development.

Abstract
Seckel syndrome (SS) is a rare, heterogeneous form of primordial dwarfism. The clinical delineation of this disorder has been inconsistent, using even Seckel's original criteria. As a result, probably fewer than one-third of reported cases are truly affected with SS. Among these, there have been only six familial cases, all of whom were born to normal parents, and in only one case has a detailed description of the central nervous system (CNS) anomalies been given. We describe a family in which three of eight children were affected with SS. CNS anomalies seen in our patients included agenesis of the corpus callosum, a dysgenetic cerebral cortex, a large dorsal cerebral cyst, and pachygyria, suggesting an underlying neuronal migration disorder. The parents are first cousins, representing only the second instance of consanguinity, supporting an autosomal recessive mode of inheritance.

Abstract
The Marshall syndrome is an autosomal dominant trait comprising ocular abnormalities, sensorineural hearing loss, craniofacial anomalies, and anhidrotic ectodermal dysplasia. To our knowledge, only seven additional multigenerational families have been reported since the initial description of the disorder by Marshall in 1958. We present a family in which six members in four generations are affected with apparent Marshall syndrome. We also review and compare similar disorders, such as Stickler, Weissenbacher-Zweimüller, and Wagner syndromes, and conclude that Marshall syndrome is a distinct entity.

Abstract
Pfeiffer syndrome is an autosomal dominantly inherited disorder consisting of craniosynostosis, a flattened midface with a beaked nose and ocular proptosis, and broad and medially deviated thumbs and great toes. Recently, based on clinical findings, the disorder has been divided into three subtypes: type 1, characterized by mild expression; type 2, in which clover leaf skull deformity and multiple congenital anomalies are present at birth; and type 3, which is similar to type 2, but lacks the presence of the clover leaf skull at birth. We describe a fetus in whom sonographic findings of clover leaf skull deformity, ocular hypertelorism, and varus deformity of the great toe led to the prenatal diagnosis of Pfeiffer syndrome type 2. We believe this is the second prenatal diagnosis of Pfeiffer syndrome, and the first time type 2 has been definitely identified in the second trimester of pregnancy.

Abstract
The cause of the Rubinstein-Taybi syndrome (RTS), a multiple congenital anomalies/mental retardation (MCA/MR) syndrome first described in 1963, remains obscure. Recently, a deletion of chromosomal material at 16p13.3 has been found in some patients with the disorder, but no such deletion can be identified in the majority of affected individuals. Although the disorder has been well documented to be concordant in at least 7 monozygotic twin pairs and in one non-twin sib pair, only one clear-cut case of parent-to-child transmission has been reported previously. We present here a mother and daughter, both of whom appear to be affected with RTS, strongly suggesting either autosomal or X-linked dominant transmission. The paucity of previous cases of parent-to-child transmission may be related to either decreased fertility or decreased fitness in affected individuals.

Abstract
Since its introduction, prenatal diagnosis of chromosomal and metabolic disorder by midtrimester amniocentesis has relied upon the use of a mixture of fetal cells obtained from amniotic fluid. Little knowledge has been gained in the sorting of these cells for diagnosis of tissue-specific disorders. In an attempt to determine the contribution of fetal colonic mucosal cells to the overall amniocyte population, we used the colonic epithelial-specific monoclonal antibody (MC-Ab) 7E12H12, IgM isotype. Specimens of the small intestine, colon, buccal mucosa, kidney, urinary bladder, and umbilical cord were obtained from electively aborted normal fetuses of 12-28 weeks' gestation. All of these specimens were examined with 7E12H12 by the immunoperoxidase technique. The MC-Ab reacted with the colonic epithelial cells but not with any of the other tissues. In addition, 40 amniotic fluid samples obtained from women between 16 and 18 weeks of gestation, who underwent amniocentesis because of advanced maternal age, were tested using a fluorescent activated cell sorter. Among the amniotic fluid specimens examined, 18.4 +/- 10.3 per cent cells reacted with 7E12H12. Double immunofluorescence studies revealed that all Mc-Ab-stained cells contained secretory component, confirming that they were epithelial in origin. All fetuses whose amniotic fluid was analysed had normal karyotypes and amniotic fluid alpha-fetoprotein levels that were also normal. This study demonstrates that cell-specific Mc-Ab can be used to detect colon cells in the amniotic fluid and that colon cells contribute significant numbers in the mixture of amniotic fluid cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Spondyloepiphyseal dysplasia congenita (SEDC) is an autosomal dominantly inherited chondrodysplasia characterized by disproportionate short stature (short trunk), abnormal epiphyses, and flattened vertebral bodies. Manifestations are present at birth. We ascertained a 4-generation family exhibiting the clinical manifestations of the disorder. Previous evidence suggesting defects of type II collagen associated with the SEDC phenotype led us to genotype the family for various COL2A1 gene-associated RFLPs. A total of 17 affected and unaffected members of this family were studied. The family was informative for a recently discovered HinfI RFLP. No recombinants between the marker and the phenotype were found in eight informative meioses. A maximum LOD score of 3.01 was obtained at a recombination fraction of .00. Our results indicate that the SEDC phenotype in this family is caused by mutations in or very close to the COL2A1 locus.

Abstract
We describe a 46,XY newborn infant with Smith-Lemli-Opitz syndrome (SLOS) with multiple congenital anomalies including female external genitalia, a testis palpable in each labium majus, a cone-shaped cervix, and normal vagina. Additional anomalies included cleft palate, total anomalous pulmonary venous return, and striking limb defects (ectrodactyly of the left upper limb, radial aplasia, and monodactyly of the right upper limb). To our knowledge, this is the first report of SLOS associated with limb deficiency and the third associated with total anomalous pulmonary venous return. Our patient demonstrates that limb deficiencies may be a rare component manifestation in this syndrome of multiple congenital anomalies.

Abstract
We report on 3 Puerto Rican brothers with the clinical and laboratory findings of aspartylglucosaminuria (AGU). Their parents were first cousins. The affected sibs have the "cardinal" manifestations of AGU, including developmental disabilities, progressive "coarsening" of the face, and early onset of hepatosplenomegaly. Biochemical studies showed elevated levels of urinary aspartylglucosamine and very low activity of aspartylglucosaminidase(AGA) in cultured fibroblasts. With long term follow-up, previously undescribed manifestations were noted, including radiographic evidence of spondylolysis and spondylolisthesis in early childhood and development of macro-orchidism during puberty. This family shows that AGU is not limited to individuals of Finnish background, but that the gene is panethnic in distribution and that additional changes, not previously noted, may present with advancing age.

Abstract
We developed a bedside scoring system for diagnosis of trisomy 18 in the immediate neonatal period. Points are assigned for the presence of features known to occur in trisomy 18: five points for the presence of features previously reported in 50% or more of affected infants; three points for features reported to occur in between 10% and 50% of affected individuals; and one point for features known to occur in less than 10% of infants with the disorder. Using the scoring system, we evaluated two cohorts of patients: those in whom a diagnosis of trisomy 18 was previously established (retrospective group) and those in whom the diagnosis was suspected but not yet proved (prospective group). The average score in the retrospective series (n = 25) was 96.7, and no patient scored less than 70. Twenty-two patients were evaluated prospectively; in all cases the presence or absence of trisomy 18 was correctly predicted. The average score in the 11 patients without trisomy 18 was 41.4, and all patients scored 60 or less. In the 11 patients confirmed to have trisomy 18, the average score was 94.3, with a range of 70 to 113. This scoring system is an accurate, reproducible method for predicting trisomy 18 in neonates with multiple congenital malformations.

Abstract
We encountered three women from three generations of the same family with features of focal dermal hypoplasia (FDH). Two of the patients, the proposita and her mother, demonstrated severe manifestations, including skin, dental, skeletal, and visceral abnormalities. The proposita's grandmother, the first family member affected, had very mild expression, with aplasia cutis congenita and dental caries as the only features expressed. This family illustrates both the marked variability of expression and the proposed X-linked dominant mode of inheritance of FDH. We postulate that early embryologic random inactivation of the X chromosome bearing the mutant gene responsible for FDH is the cause of the variable expression.

Abstract
Six cases of the McKusick-Kaufman syndrome (MKS), including two cases that were diagnosed prenatally, were studied. Review of the 54 previously described cases indicates that postaxial polydactyly and hydrometrocolpos in female patients are the hallmark features of this entity. Other manifestations, such as malformations of gastrointestinal, cardiovascular, and ophthalmic structures, occur less consistently. Affected children require careful medical follow-up. Recurrence of hydrometrocolpos following surgical repair may lead to serious sequelae, such as chronic renal failure. We believe that MKS is a distinct panethnic genetic entity, inherited in an autosomal recessive fashion, and that the diagnosis should be made only in female patients with hydrometrocolpos and polydactyly or in male patients with polydactyly who have an affected female relative.

Abstract
We present the clinical findings in two children with the Setleis bitemporal "forceps marks" syndrome. The striking features include the following: (1) bitemporal scarring, an anomaly that resembles forceps marks; (2) periorbital puffiness with wrinkling of the skin; (3) abnormalities of the eyebrows; (4) anomalies of the eyelashes; (5) flattening of the nasal bridge with a bulbous nasal tip; (6) increased mobility of the skin, associated with severely redundant facial soft tissue; and (7) normal growth and development. The evidence that suggests that this unusual syndrome is inherited in an autosomal recessive fashion includes the following: (1) seven of the patients have come from the relatively isolated towns of San Sebastian and Aguadilla in Puerto Rico; (2) two sets of affected siblings have been described, and, in both cases, the siblings' parents were normal; and (3) one of the children described herein is the product of a consanguineous mating. Although the pathogenetic mechanism is unknown, Setleis syndrome is clearly inherited as an autosomal recessive trait.

Abstract
Computed tomographic (CT) scans of the brain in a child with Smith-Lemli-Opitz syndrome revealed enlargement of the ventricular system, hypoplasia of the cerebellum, and abnormal thickening of the gray matter, consistent with pachygyria. These findings have been previously noted in autopsies performed on patients with this disorder. We conclude that CT scanning is a valuable tool in the evaluation of children suspected of having the Smith-Lemli-Opitz syndrome.

Abstract
To objectively evaluate the fetal acquired immunodeficiency syndrome, we have developed a scoring system based on the presence of the characteristic features that we have previously reported. Using this scoring system, 37 children seropositive for the human immunodeficiency virus were classified into three groups: dysmorphologically severely affected (12 children); moderately affected (15 children); and mildly affected (ten children). There was a statistically significant correlation between the severity of the dysmorphic features and both the presence of opportunistic infections within the first year of life and the age at onset of symptoms associated with immune dysfunction, with the more severely stigmatized children manifesting symptoms at a younger age. There was no correlation, however, between severity of the dysmorphic features and presence of opportunistic infections at the time of our examination. We conclude that this scoring system may be useful in presymptomatic identification of severely dysmorphic human immunodeficiency virus-infected infants.

Abstract
We report a case of a black infant who died at 9 months of age with clinical and pathological findings consistent with the acute neuronopathic form of Gaucher disease (Type 2). Analysis of peripheral blood platelets obtained from this child demonstrated very low levels of beta-glucosidase activity. beta-hexosaminidase (HEX) activity in the serum, however, was 30 times greater than the level in control sera and 15 times greater than the level observed in individuals affected with the chronic form of Gaucher disease (Type 1). Similarly, alpha-D-mannosidase (MANN) activity in the proband's serum was significantly elevated when compared with controls, and chronic Gaucher disease patients. We postulate that the cause of the elevation of these lysosomal enzymes is similar to the cause of elevation in Type 1 individuals but that patients with Type 2 Gaucher disease have a more serious cellular defect.

Abstract
Twenty infants and children with positive serologic tests for the human T-cell lymphotropic virus type III (HTLV-III) were noted to have similar features including growth failure (75%), microcephaly (70%), and craniofacial abnormalities consisting of ocular hypertelorism (50%); prominent box-like appearance of the forehead (75%); flat nasal bridge (70%); mild upward or downward obliquity of the eyes (65%); long palpebral fissures with blue sclerae (60%); short nose with flattened columella and well-formed, triangular philtrum (65%); and patulous lips (60%). These features constitute a new and distinct dysmorphic syndrome, the HTLV-III embryopathy.
