RT Journal Article SR Electronic T1 A new approach to the elucidation of complex chromosome rearrangements illustrated by a case of Rieger syndrome. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 234 OP 237 DO 10.1136/jmg.35.3.234 VO 35 IS 3 A1 Ogilvie, C M A1 Raymond, F L A1 Harrison, R H A1 Scriven, P N A1 Docherty, Z YR 1998 UL http://jmg.bmj.com/content/35/3/234.abstract AB A patient with a complex chromosome rearrangement and unilateral Rieger syndrome is presented. This rearrangement involves four chromosomes and six breakpoints, one of which is at 4q25, the candidate region for Rieger syndrome. We discuss a novel approach to the elucidation of this case using a multiprobe fluorescence in situ hybridisation method to show rearrangements unpredictable from G banded analysis, and the clear and unambiguous presentation of the karyotype using computer generated colour ideograms.
