Assignment of the human ARNO3 gene (PSCD3) to chromosome 7p21 by radiation hybrid mapping

The chromosomal localization of the human ARNO3 gene (PSCD3) was determined using monochromosomal somatic cell hybrid and radiation hybrid mapping panel. PCR analysis of a hybrid DNA panel localized the ARNO3 gene to human chromosome 7. The analysis of the Genebridge4 radiation hybrid panel using PCR amplification located the ARNO3 gene between NIB1822 (9.5 cR) and D7S481 (5.5 cR) with a lod score of > 3.0. This region is located in the human chromosome band 7p21.
