title: Eukaryotic translation termination factor gene (ETF1/eRF1) maps at D5S500 in a commonly deleted region of chromosome 5q31 in malignant myeloid diseases.
abstract: The human genome contains four ETF1 (eukaryotic translation termination factor 1) homologous sequences, localized on chromosomes 5, 6, 7 and X, and corresponding to a functional gene on chromosome 5 and three processed pseudogenes on the other chromosomes. ETF1 genomic or cDNA probes were mapped by fluorescence in situ hybridization to 5q31, 6p21, 7q11 and Xp11.4-->p11.1. A microsatellite marker (D5S500) was identified in intron 7 of the functional ETF1 gene providing its exact position in the 5q31 band. Thus, the ETF1 gene is located in a 5q region which contains unidentified genes responsible for genetic or malignant disorders, and it might be considered as a candidate gene involved in the pathogenesis of these diseases.
