title: A physical map of the human PI and AACT genes.
abstract: We have used probes from the human genes PI, PIL, and AACT (alpha 1-antitrypsin, alpha 1-antitrypsin-related sequence, and alpha 1-antichymotrypsin) to make a pulsed-field map of the surrounding region of 14q31-32. We have discovered that the PI-PIL gene cluster is only 220 kb away from the AACT gene and that it is orientated in the opposite direction. The comparatively short distance between the genes comes as a surprise given previous estimates of the level of genetic recombination between them.
