Delineation of a critical region on chromosome 18 for the del(18)(q12.2q21.1) syndrome

Abstract excerpt

Deletions involving the long arm of chromosome 18 have been reported in many patients. Most of these deletions are localized in the distal half of the long arm (18q21.1 --> qter) and are detectable by standard cytogenetic analysis. However, smaller interstitial deletions leading to a recognizable phenotype and residing in the region around chromosome band 18q12.3 (bands q12-q21) are less common. Here we report on...
