title: Autoimmune polyglandular disease type I. Exclusion map using amplifiable multiallelic markers in a microtiter well format.
abstract: The pathogenetic background of human autoimmunity is only partially understood. By discovering the defective gene causing the autosomal recessive polyglandular autoimmune disease type I (PGD I, APECED) we hope to provide new insights into autoimmune responses in general. Here we have taken advantage of newly developed amplifiable multiallelic microsatellite markers and performed the analyses using the microtiter well format of the polymerase chain reaction. This rapid semiautomated protocol was applied to analyze 62 assigned highly polymorphic loci. The linkage analyses coupled with the EXCLUDE analysis resulted in an exclusion map of this polyglandular autoimmune disease and in the preliminary assignment of the APECED locus to chromosome 22. The method proved to be an effective and economical tool for gene mapping compared with standard blotting and hybridization.
