title: A bisatellited marker chromosome in an infant with the caudal regression anomalad.
abstract: An infant with the caudal regression anomalad is described. Karyotypic analysis revealed mosaicism for a bisatellited microchromosome. Using banding techniques, an attempt was made to further identify the marker chromosome. It is suggested that a causal relationship exists between the cytogenetic findings and the clinical observations.
