Abstract
We describe a 20-point linkage analysis map of chromosome 11q22-23 tha t is based on genotyping 249 families (59 CEPH and 190 A-T). Monte Car lo linkage analyses of 176 ataxia-telangiectasia (A-T) families locali zes the major A-T locus to the region between S1819(A4) and S1818(A2). When seven nonlinking families were excluded from subsequent analyses , a 2-lod support interval of similar to 500 kb was identified between S1819(A4) and S1294. No recombinants were observed between A-T and ma rkers S384, B7, S535, or S1294. Only 17 of the international consortiu m families have been assigned to complementation groups, The available evidence favors either a cluster of A-T genes on chromosome 11 or int ragenic defects in a single gene.
