WilliamsBeuren syndrome:genes and mechanisms
Howard Hughes Medical Institute and Department of Genetics,Stanford University School of Medicine, Stanford, CA 94305-5323,USA
ABSTRACT
WilliamsBeuren syndrome (WBS; OMIM 194050)is caused by heterozygous deletions of ~1.6 Mb of chromosomal sub-band7q11.23. The deletions are rather uniform in size as they arisespontaneously by inter- or intrachromosomal crossover events withinmisaligned duplicated regions of high sequence identity that flank thetypical deletion. This review will discuss the status of the molecularcharacterization of the deletion and flanking regions, the genesidentified in the deletion region and their possible roles in generatingthe complex multi-system clinical phenotype.
