Our laboratory previously described the independent isolation of the fibroblast growth factor 4 (FGF-4) gene by NIH3T3 transformation assay using DNA from a patient with CML leukemia (Lucas et al., 1994). The FGF-4 gene was truncated by DNA rearrangement with a novel gene named GRS. In this manuscript we describe isolation of GRS cDNA and show by sequence comparison that GRS is a novel member of the Bcl-2 gene family. Northern analysis shows expression of the gene in normal human tissue to be largely restricted to the hematopoietic compartment. Analysis of the pattern of gene expression in cancer cell lines demonstrates GRS is expressed in hematopoietic malignancies and in melanoma. The chromosomal location of GRS has also been determined. The gene is positioned on chromosome 15 within bands q24-25.
