    Abstract:
    The genes for PGI (biglycan, BGN) and PGII (decorin, DCN) have been assigned to human chromosomes X and 12 by Southern analysis of a panel of human-rodent somatic cell hybrid DNAs with cDNA probes for these related small proteoglycans. Regional localization of BGN to Xq13-qter and DCN to 12p12.1-qter was also obtained by examining hybrids containing spontaneous breaks or well-characterized translocations involving chromosomes X and 12. Biglycan (BGN) is a single-copy gene about 6 kb in length. Hybridization with subfragment cDNA probes suggests the presence of two copies of the decorin (DCN) gene, or related sequences, at the locus on chromosome 12, although there is no evidence for function of more than one DCN gene. Efforts to detect restriction fragment length polymorphisms with these probes were unsuccessful.
