in view of the fact that the t cell receptor beta-chain locus has been mapped to chromosome 7 , and that the disease ataxia telangiectasia ( at ) is associated both with abnormal t cell function and with chromosomal abnormalities of the same region of chromosome 7 , we investigated the possibility that the polymorphism could demonstrate linkage of the t cell receptor locus to the gene for that disease .
