RNA helicase A is the homolog of the Drosophila maleless protein, an essential factor involved in dosage compensation, and plays a crucial role in early development in mammals. Here, we have mapped the human RNA helicase A (DDX9) gene to the major susceptibility locus for prostate cancer at chromosome band 1q25, and its pseudogene (DDX9P) to the band 13q22 by fluorescence in situ hybridization, somatic cell hybrid analysis, and assignment of YAC clones, respectively.
