Chromosome 18 variant with increased centromeric tandemly repeated DNA in a family
Abstract
At amniocentesis of a woman in her forties, a familial abnormal chromosome 18 is found. The very elongated short arm is shown to consist partially of centromeric heterochromatin of 18 by specific DNA probe. The newborn develops normally.
