A new syndrome characterized by cleft palate, coloboma, hypospadias, deafness, short stature, and radial synostosis has been described. The family history suggests either an autosomal dominant mode of inheritance with limited expression in females or X-linkage. Other syndromes with similar phenotypes and modes of inheritance are discussed. The need for accurate and complete family histories in cases involving cleft palate and cleft lip/palate is discussed in relation to genetic counselling and recurrent risk estimates.

An eight month old girl was born with symmetrical bilateral oblique facial clefts and calcaneovarus foot deformity. CT scan of the head showed severe bilateral ocular hypoplasia and normal brain parenchyma. Peripheral blood karyotype showed a de novo balanced translocation between a chromosome 1 and 22. A submicroscopic imbalance secondary to this translocation cannot be ruled out. The pattern of the observed anomalies will help distinguish between oblique facial clefts and amniotic band disruption. Chromosomal studies should be performed in children with such rare malformations. [ABSTRACT FROM PUBLISHER]

Linkage relationships of the gene for peripheral neurofibromatosis (NF) were assessed in a large American Caucasian pedigree using two DNA markers located on chromosome 8. Linkage to the thyroglobulin locus, located at 8q24, was excluded (lod less than or equal to -2.0) to 21 cM. Data obtained for the tissue plasminogen activator locus, located at 8p12, excluded linkage to 4 cM. These results exclude between 20 to 30% of chromosome 8 as a possible map location for the NF gene in this family. Comparison of the two DNA markers excluded their linkage to 0.5 cM.
