1/2. Agenesis of the corpus callosum associated with DiGeorge-velocardiofacial syndrome: a case report and review of the literature.

    We report a patient with clinical and cytogenetic findings consistent with DiGeorge-velocardiofacial syndrome and agenesis of the corpus callosum. This patient represents the first report of a case of DiGeorge-velocardiofacial syndrome associated with such a central nervous system abnormality. This case, together with previous reports in the literature, suggests that structural brain abnormalities, and in particular abnormalities of the corpus callosum, are part of the complex syndrome associated with the chromosomal microdeletion 22q11.2. We suggest that the diagnosis of DiGeorge-velocardiofacial syndrome be entertained in patients with agenesis of the corpus callosum in the context of other common clinical features of this syndrome.

2/2. Segmentation anomalies of vertebrae and ribs with other abnormalities of blastogenesis: syndromes or associations?

    On the basis of two recently studied human fetuses and the historical records and remnant 19th century skeletons in the Museum Vrolik in Amsterdam, we have begun an analysis of an unusual form of somite dysgenesis. This disorder includes vertebral and costal segmentation defects with or without (distal) limb malformation and deformities, anogenital anomalies, unusual colonic atresia, abdominal wall and diaphragmatic defect, central nervous system abnormality with large head, and severe neurohypotrophic lower limb deformities. This study suggests the existence of an axial vertebral/costal dysgenesis complex with apparently or nearly normal number of cervical vertebrae. There also is some overlap with lumbosacral agenesis but different from the autosomal recessive entities Jarcho-Levin syndrome or spondylocostal dysostosis. To date, no associated heart defects have been noted.
