Abstract:
A human cDNA for biglycan (BGN) has recently been mapped to proximal Xq28. We have mapped the murine locus, Bgn, approximately 50 kb distal to DXPas8, using a combination of genetic mapping in an interspecific backcross of B6CBA-Aw-J/A-Bpa x Mus spretus and physical mapping using pulsed field gel electrophoresis and analysis of murine yeast artificial chromosomes (YACs) containing both DXPas8 and Bgn. Our mapping studies also appear to exclude Bgn as a candidate gene for the bare patches (Bpa) mutation and for the homologous human disorder X-linked dominant chondrodysplasia punctata (CDPX2).
