Abstract:
Two phage lambda clones that contain the 5' portion of the human type I inosine 5'-monophosphate dehydrogenase (IMPDH, EC 1.1.1.205) gene were isolated. Both polymerase chain reaction analysis of a panel of human-mouse and human-hamster cell somatic hybrids using primers specific for the type I IMPDH gene and fluorescence in situ hybridization with metaphase human chromosomes using type I IMPDH genomic DNA as probes indicate that the type I IMPDH gene (symbol IMPDH1) is located on chromosome 7. Sequential GTG-banding was performed to assign the band location of the type I IMPDH gene to chromosome 7q31.3-q32.
