title: A radiation hybrid map of human chromosome 11q22-q23 containing the ataxia-telangiectasia disease locus.
abstract: We describe a high-resolution radiation hybrid map of human chromosome 11q22-q23 containing the ataxia-telangiectasia (AT) disease gene loci. The order and intermarker distances of 32 chromosome 11q22-q23 markers were determined by a multipoint maximum likelihood method of analysis of the cosegregation of markers in 100 radiation hybrids. The radiation hybrid map of polymorphic loci was consistent with genetic linkage maps of common markers. Several genes, including alpha B-crystallin, adrenal ferrodoxin, CBL2, collagenase, dopamine receptor type 2, neural cell adhesion molecule, progesterone receptor, and stromelysins 1 and 2, were placed in relation to previously ordered, genetically mapped polymorphic loci. Five new markers (alpha B-crystallin, adrenal ferrodoxin, CJ52.114, CJ52.3, and D11S535) were ordered within the current published flanking markers for the AT group A and group C disease loci. A candidate AT group D gene (ATDC) identified by Kapp et al. (1992, Am. J. Hum. Genet. 51: 45-54) was mapped telomeric to THY1, outside the flanking markers identified by multipoint linkage analysis for the major AT locus.
