A translocation at 12q2 refines the interval containing the Holt-Oram syndrome 1 gene

Am J Hum Genet. 1996 Dec;59(6):1337-41.

Abstract

A gene for Holt-Oram syndrome (HOS) has been previously mapped to chromosome 12q2 and designated HOS1. We have identified a HOS patient with a de novo chromosomal rearrangement involving 12q. Detailed cytogenetic analysis of this case reveals three breaks on 12q, and two of these are within the HOS1 interval. By using a combination of chromosome painting and FISH with YACs and cosmids, it has been possible to map these breakpoints within the critical HOS1 interval and thus provide a focus for HOS gene-identification efforts.
