The FAU gene is the cellular homologue of the viral FOX sequences in the genome of the Finkel‐Biskis‐Reilly murine sarcoma virus (FBR‐MuSV); the viral FOX sequences have been shown to increase the transforming capacity of FBR‐MuSV in vitro. The human FAU gene has recently been isolated, characterized, and mapped to chromosome band 11q13. Here, we report results of fluorescence in situ hybridization (FISH) analysis which indicate that the FAU gene maps proximally to the putative oncogene BCL1 at 11q13. Furthermore, we identified a t(11;17)(q13;q21) translocation in tumor cells of a t(11;14)(q13;q32)‐positive B‐cell non‐Hodgkin's lymphoma patient by FISH analysis using a FAU containing cosmid clone as molecular probe and by double‐colour chromosome painting analysis using chromosome 11‐ and chromosome 17‐specific painting probes. The position of the chromosome 11 breakpoint of the t(11;17) translocation was pinpointed to a human DNA region around the FAU gene of about 40 kbp. © 1993 Wiley‐Liss, Inc.
