The chromosomal localisation of the human gene coding for peroxisomal
3-oxoacyl-CoA thiolase (ACAA) was determined by human-hamster somatic
cell hybrids and fluorescence in situ hybridisation, using cDNA and ge
nomic probes, respectively. The results allowed an exclusion of the pr
eviously suggested presence of a second site for ACAA on chromosome 11
and an assignment of the gene to a single chromosome band (3p22).
