title: Molecular analysis of the human serum amyloid A (SAA) gene family.
abstract: We have assigned the human serum amyloid A (SAA) gene family to a 90 kb region on the short arm of human chromosome 11 (11p) by hybridization of defined genomic fragments of human SAA genes to DNA from rodent-human somatic cell hybrids and to large DNA fragments separated by transverse alternating field gel electrophoresis. We have also characterized SAA probe hybridization patterns in human DNA cleaved with restriction endonucleases Hind III, Pst I, BglII, TaqI, and XbaI and found invariant patterns except for a two-allele restriction fragment length polymorphism (RFLP) with Hind III. These studies show that the SAA gene family comprises at least three members in the haploid human genome and will be useful in identifying variant patterns and establishing linkage between members of the SAA gene family and other markers on chromosome 11.
