Assignment 1 of FRA1H common fragile site to human chromosome band 1q42.1 proximal to the nuclear NAD+ ADP-ribosyltransferase gene (ADPRT) and to the main 5S rRNA gene locus

This is a more precise localization of FRA1H and ADPRT previously mapped to 1q42 (Sutherland et al., 1985; Baumgartner et al., 1992), and an ordered mapping of these two markers and of the main 5S rRNA locus mapped to 1q42.13 (Lomholt et al., 1995). I.F.: 2.27
