Alignment of VIM, MRC1, GAD2, and IL2RA genes on swine chromosome 10q by in situ hybridization and RH mapping.
Since the distal half of swine chromosome (SSC) 10q was shown to contain a quantitative trait locus (QTL) influencing swine growth, the precise correspondence between this chromosome region and the orthologous human chromosome region (HSA10p) was investigated using chromosomal fluorescence in situ hybridization and RH mapping of type I loci spanning the growth QTL. The goal was to align this critical region of swine with the corresponding region in human for the purpose of identifying candidate genes. The HSA10p type I loci mapped in swine were VIM, MRC1, GAD2, and IL2RA. Locus order on SSC10q was shown to be centromere-VIM-MRC1-GAD2-IL2RA, while in human the order is centromere-GAD2-MRC1-VIM--IL2RA, indicating that the chromosome segment marked by VIM, MRC1 and GAD2 has been inverted relative to the centromere and IL2RA.
