Abstract:
:Fluorescence in situ hybridization was used to establish the order of, and to estimate genomic distances among, members of the carcinoembryonic antigen (CEA) and pregnancy-specific glycoprotein (PSG) subgroups on chromosome 19. Fluorescence in situ hybridization to metaphase chromosomes localized the PSG subgroup telomeric to the CEA subgroup. Cosmid clones containing sequences for individual genes in the CEA and PSG subgroups were also hybridized to human sperm pronuclear and somatic interphase nuclear chromatin targets. The mapping results lead to the gene order cen-CGM7-CEA-NCA-CGM1-BGP-CGM9-CGM8-PSG-te l. The genomic distances between selected pairs of gene family members were estimated from the physical distances between hybridization sites measured in pronuclei. The CEA-PSG gene family region is estimated to span 1.1 to 1.2 Mb.
