Abstract:
Nineteen polymorphic lymphocyte proteins were previously detected by two-dimensional protein electrophoresis (2DE). In this report, we describe the genetic linkage mapping of six of these polymorphic proteins (PNIA1-PNIA6), the identification by genetic linkage of a seventh (glyoxalase 1 on 6p21), and support for the mapping of an eighth (plastin or LCP1) to near the ESD locus on Chr 13. PNIA1-PNIA6 were assigned, respectively, to 10q26, 16p13.3, 10q, 11p15, 3q, and 19q13. These genetic linkages were achieved by classical linkage analysis of 2DE protein charge polymorphisms to the panel of RFLPs previously typed in nine pedigrees in the Centre D'Etude du Polymorphisme Humain (CEPH) collection.
