Abstract

The APR, also known as LRP, gene is highly homologous to the low-density lipoprotein (LDL)-receptor and encodes a cell surface molecule with biochemical properties consistent with function as a lipoprotein receptor. This gene has been mapped to human chromosomal bands 12q13-q14, a region commonly altered in tumors of adipose cells. The proximity of APR to these breakpoints, coupled with its presumed role in lipid metabolism and possible affect on cell proliferation, suggest it as a candidate gene for adipose tissue tumor formation. Pulsed-field gel analysis was used to develop a physical map covering 750 kilobases (kb) surrounding this gene. Examination of myxoid liposarcomas and lipomas bearing the characteristic translocations (12;16)(q13;p11) or (12;variable)(q14;variable), respectively, excluded the breakpoints from within a 750-kb region surrounding the APR gene. These results suggest that APR is not involved directly in the genetic changes that underlie development or progression of these tumors.
