Trigonocephaly: a new familial syndrome.

Trigonocephaly was found in six relatives through three generations of one family. The propositus was ascertained at birth because of omphalocele. In addition to trigonocephaly, he had minor ear, vertebral, and genital abnormalities. His father had mild microcephaly, and both had minor eye abnormalities. None of the other four affected individuals had any other malformations. In this family, trigonocephaly is an autosomal dominant trait. The ratio of affected males to affected females was 5 to 1, and although the paucity of affected females is not statistically significant, we speculate that it may reflect variable expressivity or sex limitation of the trait. We conclude that the condition in this family represents a unique syndrome in which trigonocephaly is not associated with functional brain abnormalities and where craniosynostosis is limited to the metopic region.

49,XYYYY. A case report.

A 14-month-old boy with a 49,XYYYY karyotype is reported. The physical examination revealed unusual facial features, brachydactyly with clinodactyly, limitation of supination at the left elbow, and inguinal hernia. Radiological abnormalities of the skeleton and urinary tract were present, and the developmental examination showed a DQ of 70.

Asplenia and polysplenia syndromes with abnormalities of lateralisation in a sibship.

In the family presented here the first child had asplenia syndrome with cor biloculare' transposition of the great vessels, pulmonary stenosis, and anomalous pulmonary venous drainage. Another sib had situs inversus with polysplenia syndrome, including very similar cardiovascular defects and biliary atresia. The possibility that these two syndromes, namely asplenia and polysplenia, are different manifestations of a similar defect in the normal asymmetrical development of internal organs is discussed.

Normal psychomotor development in a child with mosaic trisomy and pericentric inversion of chromosome 9.

A female infant with trisomy 9 in 58% of her cells is reported. Multiple congenital malformations were present, but she had normal psychomotor development. A pericentric inversion involving a portion of the centromeric heterochromatin of chromosome 9 was identified in the patient and her mother. This variant chromosome 9 was present in duplicate in the trisomic line. Since similar variants of 9qh have been found repeatedly in this syndrome, we feel that this association may be a non-random one.

Unilateral radial aplasia and trisomy 22 mosaicism.

A child with unilateral radial aplasia, asymmetry, other malformations, and severe physical and mental retardation is reported. In blood and bone marrow cultures a low mosaicism for trisomy 22 was found. In a few cells a chromosome 22 was missing. The importance of early cytogenetic analysis on large numbers of cells is emphasised, especially in cases of asymmetry where mosaicism is suspected.

The genetics of the aryl sulfatase A locus.

A genetic analysis was performed in an isolate in which metachromatic leukodystrophy (MLD) and aryl sulfatase A (ASA) pseudodeficiency are relatively frequent. The frequency of matings at risk and the frequency of ASA pseudodeficiency among parents of MLD patients are compatible with allelism between the gene determining MLD and the gene determining ASA pseudodeficiency. Two independent pedigrees including MLD patients and ASA-deficient healthy individuals also fit the model of allelism.

Metachromatic leukodystrophy in the habbanite Jews: high frequency in a genetic isolate and screening for heterozygotes.

A very high incidence of late infantile metachromatic leukodystrophy (MLD) (1/75 live births) was found in the Jewish Habbanite community which constitutes a genetic isolate of about 1,000-1,200 individuals. Screening in this population for aryl sulfatase A (ASA) levels in married adults revealed a carrier frequency for MLD of 17% and identified six couples of whom both partners were heterozygotes (6% of screened couples). In three pregnancies of these couples, prenatal diagnosis for the detection of ASA in the fetus was performed.

Pure trisomy 17p in 60% cells.

A patient with pure trisomy of the short arm of chromosome 17 in 60% of the examined cells is reported. She presented a variant chromosome 1 with partial pericentric inversion and increased centromeric heterochromatin in one chromosome 17. The cytogenetic findings are discussed. The clinical findings are compared to those found in other reported cases of partial trisomy 17 and a delineation of a pure trisomy 17p attempted.

Triple mosaicism 45,XY,--18/46, XY/47,XY,+18.

A patient with symptoms clinically resembling Edwards's syndrome is presented. Cranial asymmetry, thoracic and lumbar hemivertebrae, and an additional rib were the unusual features. The cytogenetic studies revealed the coexistence of three separate cell lines with 45,XY,--18/46,XY/47,XY,+18 complement.
