The mobile nature of acrocentric elements illustrated by three unusual chromosome variants.
Human genetics - 1 Jun 1998

Abstract excerpt
Variant chromosomes are polymorphic in areas that are rich in repeat sequences such as the pericentromeric regions or in the acrocentric short arm regions. The dynamic nature of these regions is evident in the polymorphisms they exhibit. In this paper three unusual variants are described: a chrom...
