A specific chromosomal translocation, t(2;13)(q35;q14), is present in tumor cells from about one-half of children with alveolar rhabdomyosarcoma, who generally have widely disseminated disease at diagnosis. Using a series of six DNA probes from five loci previously assigned to bands 13q12----q14, we have localized the translocation breakpoint on chromosome 13 by in situ hybridization. Each probe was used to examine metaphase spreads from two or more rhabdomyosarcoma cell lines that have the t(2;13), as well as from control lymphoblastoid cell metaphases. All six probes bound to chromosome 13q12----q14 in the control cell line, but showed no appreciable hybridization to other sites. With rhabdomyosarcoma metaphases, cDNA clones of the retinoblastoma susceptibility gene (RB1) and the esterase D gene (ESD), as well as the arbitrary genomic fragment 7D2 (D13S10), showed specific hybridization to the normal chromosome 13 and the der(2) marker, but not to the der(13). By contrast, the genomic fragments HU10 (D13S6) and 7F12 (D13S1) hybridized specifically to the normal chromosome 13 and the der(13), but not to the der(2). Thus, the breakpoint of this translocation lies distal to D13S6 and D13S1 and proximal to ESD, RB1, and D13S10. Our data indicate that the locus affected by the translocation breakpoint on chromosome 13, which we have termed RMS, is physically distinct from the RB1 locus and is, in fact, proximal to ESD, which others have placed at least 10(6) bp proximal to RB1. The consistent presence of the der(2) marker chromosome, coupled with occasional loss of the der(13), suggests that the RMS gene, or at least a critical component, moves to chromosome 2 in tumors with this translocation.
