Peters' anomaly and associated congenital malformations.

We reviewed the clinical findings in 29 patients with Peters' anomaly. There was developmental delay in 15 patients, congenital heart disease in eight patients, external ear abnormalities in five patients, structural defects of the central nervous system in four patients, genitourinary malformations in four patients, cleft lip/palate in three patients, hearing loss in three patients, spinal defects in two patients, and single cases of other less common defects. One patient had fetal alcohol syndrome; one, Pfeiffer's syndrome; and one, short stature, ulnar hypoplasia, and joint laxity. Colobomatous microphthalmia was present in seven patients, and persistent hyperplastic primary vitreous in three patients. Ten patients developed glaucoma, and three had retinal detachment unrelated to ocular surgery. Peters' anomaly may be due to a developmental field defect, or the complex ocular and systemic malformations may be the result of a contiguous gene syndrome or of a defective homeotic gene controlling the development of the eye and other body structures.

Craniofacial anomalies and malformations in respiratory chain deficiency.

We report on facial anomalies including round face, high forehead, flat philtrum, apparently low-set ears, and short neck in 4 unrelated patients with mitochondrial respiratory enzyme deficiency. Pre- and postnatal growth retardation with microcephaly, brachydactyly, and hypoplasia of distal and middle phalanges was present in all 4 cases. The diagnosis of respiratory chain deficiency was confirmed by enzymatic and molecular studies. The combination of facial anomalies, prenatal growth failure, and malformations is suggestive of antenatal expression of the disease, and raises the question of the part that respiratory chain deficiencies play in human malformations.

Esophageal atresia with distal tracheoesophageal fistula in a patient with fronto-metaphyseal dysplasia.

Fronto-metaphyseal dysplasia (FMD) is an uncommon but clinically striking condition affecting bone and connective tissue. The terms used to define this syndrome fail to cover all the reported findings, the abnormalities not being confined to the metaphyses and to the frontal bones. We report on a patient who, in addition to the clinical manifestations characteristic of the syndrome, showed esophageal atresia with distal tracheoesophageal fistula. Particular emphasis is given to the extraskeletal manifestations of the syndrome reported in the literature.

Associated anomalies in individuals with polydactyly.

An epidemiological analysis of the association of polydactyly with other congenital anomalies was performed in 5,927 consecutively born polydactyly cases. They were grouped into three categories: duplicated fifth digit, duplicated first digit, and rare polydactylies; also into isolated or associated groups, if other birth defects were or were not observed in the same infant. Associated cases were further subdivided into: combined, if the other defect was a limb defect; syndromic, if a non-limb defect constituted a recognized causal or pathogenetic entity; and MCA, if a non-limb defect did not constitute a recognized entity. In 14.6% of the 5,927 polydactyly cases studied, polydactyly was not the only congenital anomaly. This associated proportion was minimal for postaxial (11.8%), intermediate for preaxial-I (20.0%), and maximal for rare polydactyly (54.9%). Duplication of the fifth toe plus syndactyly of fourth and fifth toes, as well as other syndactylies adjacent to the duplicated digit is the most frequent type. Syndactyly of fourth and fifth toes was also combined with a duplicated fifth finger, suggesting the existence of an arrested or amputated in utero sixth toe. Polydactylies are rarely associated with other congenital anomalies except in recognizable syndromes. When syndromes are excluded, most of the significant positive associations disappear. Trisomy 13, Meckel, and Down syndrome explained 255 of the 338 syndromic polydactyly cases. Down syndrome is strongly associated with first-digit duplication, and negatively associated with postaxial polydactyly. The latter could not be explained by maternal age differences among Black and non-Black case sub-sets.

Possible isochromosome 22 leading to trisomy 22.

We describe the first case of trisomy 22 resulting from a monocentric, possible isochromosome 22. The female infant had multiple anomalies including an abnormal face, ambiguous genitalia, and both ventricular and atrial septal defects. Survival was short.

Prenatal diagnosis of hypoparathyroidism retardation and dysmorphism (HRD) syndrome.

We used linkage analysis for prenatal diagnosis of the recently reported hypoparathyroidism, retardation, and dysmorphism (HRD) syndrome. Five cases from four families were evaluated. Three fetuses were carriers and were born healthy. Two fetuses were affected but the parents decided not to terminate the pregnancies. The diagnosis of HRD syndrome was confirmed in these newborns. This is the first report about prenatal diagnosis of HRD syndrome.

Apparently nonmosaic trisomy 22: clinical report and review.

We report on apparently nonmosaic trisomy 22 in a liveborn girl with multiple congenital anomalies. The abnormalities were growth retardation; microcephaly; hypertelorism; epicanthic folds; anti-mongoloid slant; apparently low-set, malformed ears; highly arched, cleft palate; short webbed neck; and hypoplastic nails. The extra 22 was found to be of maternal origin by chromosome polymorphism.

Using log-linear models to test for associations among congenital malformations.

Log-linear models can be used to test for pairwise associations and higher order interactions among anatomically distinct birth defects or congenital malformations. A log-linear model, including terms for every possible pairwise association among seven severe and easily detectable congenital malformations, was examined using data on 16,217 infants registered in the Metropolitan Atlanta Congenital Defects Program between 1968 and 1986. The resulting model showed clear patterns of strong association between some congenital malformations and not others, and the presence of 3-way interaction terms where the association between two malformations depended on the presence of a third. Examining a more parsimonious log-linear model showed overlapping patterns of pairwise association involving anal-rectal atresia and omphalocele, anal-rectal atresia and limb deficiency, and anal-rectal atresia and tracheaesophageal fistula. A second common pattern involved a triangular cluster with a hierarchical relationship among the three malformations (where there was a strong association between the first and second malformations and between the first and third malformations, but the association between the second and third was only seen in the absence of the first). Three such overlapping triangular clusters were identified from these data: neural tube defects, oral clefts, and omphalocele; neural tube defects, oral clefts, and limb deficiency; and limb deficiency, diaphragmatic hernia, and neural tube defects.(ABSTRACT TRUNCATED AT 250 WORDS)

Congenital defects of lower limbs and associated malformations: a population based study.

As part of a detailed study of limb defects and associated patterns of congenital malformations, cases with lower limb deficiencies were analysed separately. We identified a total of 130 cases with deficiencies of the lower limbs without defects of the upper limbs. This gives an incidence of 1.07/10,000 livebirths, or 1/9,337 for this group of limb defects. Most common were femur deficiencies and deficiencies of the foot. A preponderance of males was found in the group of transverse defects of the leg (fibula/tibia deficiencies) and central axis deficiencies, while females had significantly more often longitudinal tibia defects and preaxial ray defects.

Sclerocornea, hypertelorism, syndactyly, and ambiguous genitalia.

We present a child with an MCA pattern of sclerocornea, hypertelorism, pterygium colli, upper limb syndactyly, ambiguous genitalia, abnormal ears and nose, umbilical hernia, congenital heart disease, and normal chromosomes (46,XX). Although the defects observed in this case follow the diagnostic criteria for Fraser syndrome proposed by Thomas et al. [1986: Am J Med Genet 25:85-98], we think that this is a different entity.

Fryns syndrome survivors and neurologic outcome.

Fryns syndrome is an autosomal recessive multiple congenital anomaly syndrome characterized by diaphragmatic hernia, unusual facies, and distal limb hypoplasia. It was first reported as a lethal condition. We report on a three-year-old survivor with Fryns syndrome, and provide a review on the outcome of other survivors. Patients who survive the neonatal period represent 14% of reported cases. Characteristics of survivors include less frequent diaphragmatic hernia and milder lung hypoplasia, absence of complex cardiac malformation, and neurologic impairment. Multiple central nervous system abnormalities have been reported in Fryns syndrome, including agenesis of the corpus callosum, Dandy-Walker abnormality, cerebellar heterotopias, cerebellar hypoplasia, enlarged ventricles, and hypoplasia of the olfactory bulbs. Our patient exhibited profound mental retardation. He had malformations of gyration and sulcation, particularly around the central sulcus, and hypoplastic optic tracts beyond the optic chiasm. Understanding of long-term outcome of survivors is important for counseling of families with Fryns syndrome. Careful brain examination is advised; however, a normal radiological brain examination does not preclude developmental delay. The spectrum of individual outcome and of associated anomalies indicates that individual evaluation, including imaging for structural brain malformation, is strongly advised.
