bone marrow analysis at presentation revealed two chromosomally abnormal clones that shared an interstitial deletion of the long arm of chromosome 5 ( 5q- ) and a terminal deletion of the short arm of chromosome 12 ( 12p- ) , but that differed from one another in the localization of a very similar segment of chromosome 17 ( i.e . 17q11-12qter ) on two clearly distinct karyotypic sites : 2q37 and 17q25 .
