Limb-girdle muscular dystrophy (LGMD) is a genetically and clinically heterogeneous group of disorders. We previously localized an autosomal dominant form of the disorder (LGMD1A) to chromosome 5q22-31 by linkage analysis in a single large pedigree. After developing a microsatellite genetic map incorporating six loci in q31-33 of chromosome 5 and spanning 35 cM, we have refined the original localization. Using multipoint analysis, LGMD1A is localised to a 7 cM region between the markers IL9 and D5S178 with odds > 1000 : 1.
