Chromosomal localization of the genes encoding ALDH, BMP-2, R-FABP, IFN-γ, RXR-γ, and VIM in chicken by fluorescence in situ hybridization

Six structural genes encoding ALDH, BMP-2, R-FABP, IFN-gamma, RXR-gamma and VIM were mapped in the chicken by fluorescence in situ hybridization (FISH) using genomic and cDNA clones as probes. The genes were found to be located on four different macrochromosomes: chromosome 1 (IFNG and FABP), chromosome 2 (VIM and ALDH), chromosome 3 (BMP2) and a smaller macrochromosome, most probably chromosome 7 (RXRG). With the exception of IFNG none of the newly mapped sites corresponds to known orthologous regions between chicken and human chromosomes.
