Sagittal craniosynostosis, Dandy-Walker malformation, and hydrocephalus: a unique multiple malformation syndrome.

The Dandy-Walker malformation and craniosynostosis have each been described as isolated occurrences and as components of multiple malformation syndromes. The purpose of this report is to delineate the characteristics of a multiple malformation syndrome of Dandy-Walker malformation and sagittal craniosynostosis. The inheritance pattern appears to be autosomal dominant.

Holoprosencephaly and primary craniosynostosis: the Genoa syndrome.

We report on 2 sibs with holoprosencephaly of the semilobar type, unusual facial appearance not diagnostic of holoprosencephaly, and primary craniosynotosis involving the coronal and lambdoid sutures. The condition represents a newly recognized syndrome, possibly having autosomal recessive inheritance.

Craniosynostosis and hemizygosity for D7S135 caused by a de novo and apparently balanced t(6;7) translocation.

Craniosynostosis (CRS) is frequently seen in the del(7p) syndrome, and the gene for this cranial anomaly (CRS1) has been assigned to 7p21. We present a 3-year-old boy with CRS involving the sagittal and coronal sutures, who had a de novo and apparently balanced translocation, t(6;7)(q16.2;p15.3). Southern blot analysis of several loci on 7p14-->pter showed that the patient was heterozygous for HOX1I and IL6, possibly homozygous for D7S149, but hemizygous for D7S135 with a loss of the paternal allele. These findings suggest the localization of a candidate gene for CRS1 to be on 7p15.3 in the close proximity to the D7S135 locus.

Jackson-Weiss syndrome: clinical and radiological findings in a large kindred and exclusion of the gene from 7p21 and 5qter.

We describe the clinical and radiological manifestations of the Jackson-Weiss syndrome (JWS) in a large South Australian kindred. Radiological abnormalities not previously described in the hands include coned epiphyses, distal and middle phalangeal hypoplasia, and carpal bone malsegmentation. New radiological findings in the feet include coned epiphyses, hallux valgus, phalangeal, tarso-navicular and calcaneonavicular fusions, and uniform absence of metatarsal fusions. Absence of linkage to eight markers along the short arm of chromosome 7 excluded allelism between JWS and Saethre-Chotzen syndrome at 7p21. No linkage was detected to D5S211, excluding allelism to another recently described cephalosyndactyly syndrome mapping to 5qter.

Six cases of 7p deletion: clinical, cytogenetic, and molecular studies.

To date, 32 cases of partial 7p monosomy have been described, 14 of which have been associated with craniosynostosis (CRS). There is considerable variation in the size and location of the deleted segment. However, CRS appears to be consistently associated with either a deletion or partial deletion 7p21-->7p22 or more rarely a deletion of 7p13-->7p14. Analysis of a panel of six 7p deletion cases (three with CRS) was undertaken using informative DNA probes, in order to characterize and define the extent of the deletions at the molecular level. There were five de novo deletions and one resulting from the unbalanced product of a paternal balanced insertion. The putative proximal CRS locus at 7p13-->7p14 does not appear to be allelic with Greig cephalopolysyndactyly syndrome. Three probe positions have been refined: pJ5.11 (D7S10) previously mapped to 7p14-->pter does not appear to map proximal to p15; TM102L (D7S135) does not map distal to p22; CRI-P137 (D7S65) maps distal to 7p13.

Craniosynostosis and kidney malformation in a case of Hennekam syndrome.

Hennekam syndrome is a rare autosomal recessive syndrome which was described for the first time in 1989. Here, we present a girl with intestinal lymphangiectasia, severe lymphedema of limbs, seizures, mild mental retardation, and facial anomalies consistent with the diagnosis of Hennekam syndrome. In addition, she had an ectopic kidney and craniosynostosis of the coronal suture, 2 manifestations not previously reported in this syndrome. While the molecular basis of Hennekam syndrome remains, as yet, unknown, this report illustrates its variable clinical expression.

Michels syndrome in a Brazilian girl born to consanguineous parents.

We report on a Brazilian girl born to consanguineous parents and presenting with craniosynostosis, telecanthus, blepharophimosis, blepharoptosis, epicanthus inversus, cleft lip and palate, skeletal defects, and hearing loss. This combination of anomalies appears to constitute the Michels syndrome.

Patient with craniosynostosis and marfanoid phenotype (Shprintzen-Goldberg syndrome) and cloverleaf skull.

Marfanoid phenotype with craniosynostosis (Shprintzen-Goldberg syndrome) is a rare disorder previously described in only 5 patients. We report on the sixth known patient with this condition. The findings which distinguish our patient from others reported previously are that she was ascertained prenatally as having a cloverleaf skull; this is the first female patient described with this condition. Postnatally, she presented with arachnodactyly, camptodactyly, and clover-leaf skull. Imaging studies of the brain documented microcephaly with malformed brain, hydrocephaly, and hypoplasia of the corpus callosum. She also had choanal atresia and stenosis, a clinical finding previously reported only once, in this disorder.

Recurrent lambdoid synostosis within two families.

We report on 2 families with multiple members who have proven or suspected lambdoid craniosynostosis. In one family the lambdoid suture was unilaterally involved in one sib, and bilaterally in the other. In the second family the propositus had unilateral lambdoid synostosis and his twin sisters each had bilateral lambdoid synostosis. Both families had another distant relative, a maternal grandmother in the first and paternal uncle in the second, who were also reported to have posterior plagiocephaly. We report these families as evidence for genetic transmission of a craniosynostotic trait which has only been rarely reported previously.

Craniomicromelic syndrome: a newly recognized lethal condition with craniosynostosis, distinct facial anomalies, short limbs, and intrauterine growth retardation.

We report on two sisters with an unusual form of craniosynostosis, protruding nasal spine, micrognathia, short limbs, lung hypoplasia, absent or hypoplastic gallbladder, short intestine with ileal distention, hypoplastic uterus, and intrauterine growth retardation. This combination of defects appears to be a newly recognized and probably autosomal recessive disorder.

Two craniosynostotic patients with 11q deletions, and review of 48 cases.

Many chromosomal abnormalities have craniofacial manifestations. One such abnormality, partial monosomy of chromosome 11q, is associated with metopic synostosis and resultant trigonocephaly. We reviewed 48 published cases of 11q deletions and translocations. Eighty percent were associated with abnormal head shape. Also commonly found were hypertelorism, ptosis of the eyelids, wide or low nasal bridge, apparently low-set malformed ears, down-turned mouth, micro/retrognathia, digital and cardiac anomalies, and psychomotor retardation. We report on two patients referred for abnormal head shape. The first case had brachycephaly, flat occiput, hypertelorism, and maxillary hypoplasia. Karyotype was 46,XY,del(11)(q24.1-->qter). The second patient had trigonocephaly, hypotelorism, posteriorly angulated ears, horizontal crease below his lower lip, syndactyly, shawl scrotum, cryptorchidism, and inguinal hernias. Karyotype showed partial trisomy of chromosome 4q as well as partial monosomy of 11q [46,XY,11,+der(11)t(4;11) (q31.3;q25)], a combination not previously reported. Deletions of 11q appear to produce a wide spectrum of abnormalities.
