Glutaric aciduria type II: review of the phenotype and report of an unusual glomerulopathy.

A male infant with glutaric aciduria II secondary to electron transfer flavoprotein: ubiquinone oxidoreductase deficiency is compared to previously reported cases of glutaric aciduria II. A common pattern of anomalies in patients with malformations (8/16) includes macrocephaly, large anterior fontanelle, high forehead, flat nasal bridge, telecanthus, and malformed ears. Abnormalities such as hypotonia, cerebral gliosis, heterotopias, hepatomegaly, hepatic periportal necrosis, polycystic kidneys, and genital defects in glutaric aciduria II are reminiscent of those in Zellweger syndrome, whereas elevations of glutaric, ethylmalonic, adipic, and isovaleric acids are quite distinctive. A unique ultrastructural alteration of the glomerular basement membrane was observed in the proposita. This manifestation may represent an early stage in renal cyst formation and provide a diagnostic criterion for glutaric aciduria II when enzyme studies are unavailable.

Cardio-facio-cutaneous (CFC) syndrome: report of a new patient.

We describe a girl with the cardio-facio-cutaneous (CFC) syndrome. She presented most of the characteristics of the new multiple congenital anomalies/mental retardation (MCA/MR) syndrome: unusual facial appearance and ectodermal symptoms, that is, abnormal hair and skin, ventricular septum defect, relative macrocephaly with large ventricles and cortical "atrophy," submucous cleft palate, and umbilical hernia. Her twin brother died shortly after birth and may have had the same malformation syndrome.

Clinical diagnosis of partial duplication 7q.

We report on two sibs with partial dup (7q), a retarded 9-month-old boy and an aborted fetus of 17 weeks' gestational age. Besides minor anomalies, the boy had frontal bossing, macrocephaly with hydrocephaly, a high forehead, and a large fontanelle. GTG banded chromosomes showed a 14p+ abnormality. Because his mother carries a balanced, de novo translocation with a breakpoint in band 7q33, the boy has a duplication of the distal portion of band 7q33 and the segment 7q34----qter. Our findings suggest that the phenotype in terminal duplications of 7q may, in some patients, be recognized clinically.

Cardio-facio-cutaneous (CFC) syndrome: report of two patients without hyperkeratotic skin lesions.

We report on two boys with the cardio-faciocutaneous (CFC) syndrome, but without hyperkeratotic skin involvement. They showed most of the manifestations of the CFC syndrome: growth and developmental retardation, relative macrocephaly, distinct facial appearance, sparse hair, and heart defects. Their skin was not hyperkeratotic, but patient 1 had mild atopic dermatitis and keloid-like depigmented spots.

Costello syndrome.

In 1971, Costello described a new syndrome in 2 patients. The major clinical findings comprise short stature; redundant skin of the neck, palms, soles, and fingers; curly hair; relative macrocephaly; depressed nasal bridge; papillomata around the mouth and nares; distinct facial gestalt; hyperextensible joints; and mental retardation. We present a third patient and review the manifestations of this condition.

Trisomy 8: an additional case with unique manifestations [correction].

We report on an infant with multiple congenital anomalies and mosaic trisomy 8 [corrected]. Clinical findings are presented, and compared with those of the 24 cases previously reported. Some unusual characteristics found in this patient include macrocephaly, an extreme degree of palatal hypoplasia, and abnormally shaped long bones.

Report of another family with Simpson-Golabi-Behmel syndrome and a review of the literature.

Simpson-Golabi-Behmel Syndrome (SGBS), an X-linked encephalo-tropho-schisis syndrome described in fewer than a dozen families, is characterized by pre- and postnatal overgrowth, "coarse" face, minor facial anomalies and, in more severe cases, multiple congenital anomalies and mental retardation. We report on 2 brothers with overgrowth, macrocephaly, polydactyly, supernumerary nipples, and characteristic facial appearance. In addition, the propositus also had pulmonic stenosis and a cleft palate. The findings present in our patients are compared to those in the original patients and to those in patients described more recently. Despite the fact that our patients have most of the minor and several of the more severe malformations, they are not mentally retarded.

Heterogeneity versus variability in megalocornea-mental retardation (MMR) syndromes: report of new cases and delineation of 4 probable types.

Megalocornea (corneal diameter > or = 13 mm) is associated with mental and neurological impairment, and minor anomalies in Neuhäuser syndrome (megalocornea-mental retardation syndrome). Here we report 4 new cases of megalocornea and mental retardation. Those unrelated patients have a consistent pattern of anomalies with possible recessive inheritance which clearly differs from that of the original patients of Neuhäuser et al. [1975]. We discuss the heterogeneity of the syndromes with megalocornea and mental retardation. Based on these cases and on a review of the literature, we suggest a provisional clinically oriented classification in 5 subtypes: (1) a recessive form type Neuhäuser (with iris hypoplasia and minor anomalies), (2) a recessive form type Frank-Temtamy (with camptodactyly, scoliosis and growth retardation), (3) a recessive type 3, including our 4 personal cases (with normal irides, severe hypotonia, relative or absolute macrocephaly and minor anomalies), (4) a possible Frydman type (with normal irides, megalencephaly and obesity), and (5) provisionally unclassifiable cases.

Further delineation of Costello syndrome.

We report on a 6-year-old girl with Costello syndrome. Main manifestations included poor postnatal growth, relative macrocephaly, curly hair, distinct "coarse" face, mild mental retardation, happy and sociable personality, loose dark skin particularly of hands and feet, acanthosis nigricans, thin deep set nails, enamel hypoplasia of teeth, and hyperextensible joints. The absence to date of perioral and nasal papillomata in this girl suggests that Costello syndrome is clinically recognizable even before appearance of such papillomata. Manifestations are compared to the four previously reported sporadic cases.

Mental retardation, structural anomalies of the central nervous system, anophthalmia and abnormal nares: a new MCA/MR syndrome of unknown cause.

We report on 2 unrelated Brazilian girls, born to nonconsanguineous parents, and presenting structural central nervous system defects, hydrocephaly, macrocephaly, craniosynostosis, prominent forehead, anophthalmia, and abnormal nares. These patients may have a previously undescribed recurrent-pattern cerebro-oculo-nasal syndrome.

Anophthalmia, cleft lip/palate, facial anomalies, and CNS anomalies and hypothalamic disorder in a newborn: a midline developmental field defect.

We describe an infant with a unique pattern of midline defects, including anophthalmia, cleft lip and palate, macrocephaly, cutis aplasia, and micrognathia. CNS anomalies including massive hydrocephalus with destruction of most recognizable structures were observed. The infant also developed panhypopituitarism, diabetes insipidus, and a seizure disorder. We postulate that this patient could represent a more complex form of the Delleman syndrome or a new morphogenetic syndrome secondary to ventral induction with extension to the developmental fields of the first and second branchial arches.

Long-chain 3-hydroxyacyl-coenzyme A dehydrogenase (L-CHAD) deficiency in a patient with the Bannayan-Riley-Ruvalcaba syndrome.

Bannayan-Riley-Ruvalcaba syndrome (BRRS) is an autosomal dominant condition of macrocephaly in combination with lipomas/hemangiomas, hypotonia, developmental delay, and a lipid myopathy. The etiology of the lipid storage myopathy has been unclear. We describe a black boy with findings of BRRS who also has a defect in long-chain fatty acid oxidation expressed in cultured skin fibroblasts as a deficiency of long-chain-L-3-hydroxyacyl-CoA dehydrogenase (L-CHAD). He also has an abnormal brain MRI and increased size of both lower limbs. We present this child because of his unusual combination of findings, and postulate that L-CHAD deficiency may be the cause of the lipid myopathy in BRRS.

Oculo-ectodermal syndrome: a new case.

We report on a girl with aplasia cutis congenita, epibulbar dermoids, and macrocephaly. To our opinion she has the same ocular-ectodermal syndrome as described by Toriello et al. [Am J Med Genet 45: 764-766, 1993].

Evidence for Ritscher-Schinzel syndrome in Canadian Native Indians.

We report on 8 (3 male, 5 female) native Canadian children with distinctive facial appearance and variable combinations of ocular colobomas, hypertelorism, macrocephaly, hand anomalies, congenital heart defects, structural CNS posterior fossa malformations, and mental retardation. These 8 children belong to 7 families; 3 of the families are related. The parents and other sibs are clinically unaffected. We think these manifestations provide evidence for Ritscher-Schinzel syndrome in native Canadian children, and we have confirmed that ocular colobomas are a common occurrence in this disorder.

Identical twins with Cohen syndrome.

We report the first case of identical female twins who satisfy the proposed diagnostic criteria for Cohen syndrome. The sisters presented with retinal degeneration, obesity and mental retardation, and had the characteristic facial appearance. The manifestations of previously reported cases of Cohen syndrome are reviewed. Unusual changes in our patients include tall stature, macrocephaly, and transient cardiomyopathy during the first year of life. These anomalies have been reported previously in other patients with Cohen syndrome, and suggest that the disorder is phenotypically heterogeneous. Precocious puberty was present in both girls; the latter findings have not been reported previously in the Cohen syndrome. Detailed metabolic and cytogenetic analysis demonstrated no abnormalities.

Infantile lethal variant of Simpson-Golabi-Behmel syndrome associated with hydrops fetalis.

Simpson-Golabi Behmel syndrome (SGBS) is an X-linked disorder characterized by pre- and postnatal macrosomia, minor facial anomalies, and variable visceral, skeletal, and neurological abnormalities. Since its first description by Simpson et al. [1975: BD:OA XI(2):18-24], a wide clinical range of cases has been reported. There is great variability in severity, ranging from a mild form associated with long-term survival to an early lethal form with multiple congenital anomalies and severe mental retardation. In 8 reported families, affected individuals died in infancy. Here we present 4 maternally related, male cousins with a severe variant of SGBS. One of these males was aborted therapeutically at 19 weeks of gestation following the detection of multicystic kidneys on ultrasound. The 3 liveborn males were hydropic at birth with a combination of craniofacial anomalies including macrocephaly; apparently low-set, posteriorly angulated ears; hypertelorism; short, broad nose with anteverted nares; large mouth with thin upper vermilion border; prominent philtrum; high-arched or cleft palate; short neck; redundant skin; hypoplastic nails; skeletal defects involving upper and lower limbs; gastrointestinal and genitourinary anomalies. All 3 patients were hypotonic and neurologically impaired from birth. With the exception of a trilobate left lung in one patient, the cardiorespiratory system was structurally normal. All patients died within the first 8 weeks of life of multiple complications including pneumonia and sepsis. Two SGBS kindreds, with moderate expression of the condition, have been mapped to Xq27. It is not known whether severe, familial cases, such as ours, are genetically distinct from and map to another locus. Final resolution of the genetic basis of the phenotypic variability in SGBS must await cloning and mutation analysis of the SGBS gene(s).

PTEN mutation in a family with Cowden syndrome and autism.

We report on a mother and son with Cowden syndrome and a PTEN mutation. The boy also exhibits autistic behavior and mental retardation, while his mother has a normal intelligence and social interaction pattern. We review the scanty literature data on the association of Cowden syndrome and autism and emphasize that the association of progressive macrocephaly and pervasive developmental disorder seems to be an indication for screening for PTEN mutations.
