Variation in the centromeric banding of chromosome 19.
The centromeric banding pattern of chromosomes 19 exhibited considerable variation. The variants were present in the majority of cells from an individual and consisted of additional dark-staining areas. There was no abnormal phenotypic effect associated with any variant and it is concluded that these additional dark-staining areas do not contain any functional genes.
