Gene: [14q/ATLS] ataxia-telangiectasia-like syndrome?; [AT ]


[1] On the basis of numerous data on association of ataxia telangiectasia (Louis-Bar) with the preferable breakage in the long arm of Chr 14, this locus was generally assumed to be linked with Chr 14 (Aurias-1986a,b and others). It was only the question of precise regional localization of the gene that was discussed (see GEM:14q112/TCL4 and GEM:14q321/TCL1).
[2] The GDB and MIM catalogues accepted the localization in Chr 11, according to Gatti-1988/89. These data are based on the results of estimation of the disease linkage with two molecular markers, which was performed with the use of multivariate segregation analysis in families (Sanal-1990). A possibility exists that the mutant product of the ataxia telangiectasia (Louis-Bar) locus in Chr 11 affects the liability of some chromosomal regions (including certain segments in the long arm of Chr 14) to spontaneous and/or radiation-induced breakage. However, it cannot be excluded that Chr 14 also has a locus, which lesions could cause ataxia telangiectasia-like syndrome."


[1] Two AT-like syndromes (not mapped) are registered in OMIM Catalogue: MIM:208910 - AT with generalized skin pigmentation and early death; MIM:208920 - AT-like syndrome.
