A giant short arm of no. 21 chromosome in mother of 21/21 translocation mongol.
Abstract
An extreme variation of the short arm of no. 21 chromosome in the mother of a 21/21 translocation mongol is described. The possible relation between the very long short arm of chromosome no. 21 in the mother and a centric fusion type of translocation mongolism in the offspring is discussed.
