Genetic and physical maps of the 1q32–42 region. The genetic map is based on the maps available at Marshfield, WI, USA (http://research.marshfieldclinic.org/genetics) and the Genome Database (http://www.gdb.org). The physical map was determined from the sequence data generated by the Human Genome Project (as described in the text), and is available from the National Center for Biotechnology Information (http://www.ncbi.nlm.nih.gov). The physical distance between the markers was estimated from the available sequence data if the markers were not on the same contig, and the maps are not drawn to scale. The physical location of D1S213 between D1S2641 and ADPRT is not known.
