Craniosynostosis and syndactyly: expanding the 11q-- chromosomal deletion phenotype.

A patient with a partial deletion (q23 leads to qter) of the long arm of chromosome 11 presented with craniosynostosis and syndactyly. These characteristics, which have not been previously reported with 11q--, expand the phenotype of this syndrome and emphasise the need for chromosome analysis with banding techniques in multiple congenital anomaly syndromes, even if the patient could be classified as having a non-chromosomal syndrome.
