title: X-linked immunodeficiency with hyperimmunoglobulinemia M appears to be linked to the DXS42 restriction fragment length polymorphism locus.
abstract: The gene involved in X-linked immunodeficiency with hyperimmunoglobulinemia M (XHM) was localized by the use of nine restriction fragment length polymorphic (RFLP) markers covering the entire X chromosome. Multipoint linkage analysis of RFLP data obtained in a three generation XHM pedigree indicates the Xq24-q27 area around the DXS42 RFLP locus as the most likely localization of the XHM locus.
