Genetic Evidence That the Gene Controlling AubIs Located on Chromosome 19

Abstract
DNA from a series of families segregating for Aub was analyzed with a genomic DNA probe which defines a Bg1 I polymorphism for apolipoprotein CII (APOC2). The investigation revealed that the genes for Aub is closely linked to APOC2 (.cxa.z = 8.43 at .cxa..theta. = 0.00) for paternal and maternal meioses combined, to LW (.cxa.z = 3.61 at .cxa..theta. = 0.00) in paternal meioses and less closely linked to SE (.cxa.z = 3.10) at (.cxa..theta. = 0.09) for combined paternal and maternal meioses. Therefore, we propose a chromosome 19 location for the Aub gene.
