Summary
Ataxia telangiectasia (A-T) is an autosomal recessive disorder characterised by progressive neurological degeneration, oculocutaneous telangiectasia, immunodeficiency and a high incidence of lymphoid tumours. A prerequisite to gaining a complete understanding of the basic defect that results in these features is the localization of the gene(s) involved. We report here a linkage analysis using seven polymorphic markers, which map to 11q22–23, on a sample of 35 consecutively obtained families from the British Isles showing this disorder. In a pairwise analysis, the strongest support for linkage was a lod score of 4.01 at zero recombination from Thy-1. This result supports a previous report showing linkage of the A-T gene to 11q22–23. We have also obtained evidence in a multipoint analysis for a more centromeric A-T-linked locus in the region between YNB 3.12/CJ52.208 and 2-7-1D6. This observation is also supported by inspection of the haplotypes of selected recombinants.
