A novel autosomal dominant limb-girdle muscular dystrophy (LGMD 1F) maps to 7q32.1-32.2

In 2001, the authors described the clinical features of a genetically distinct autosomal dominant limb-girdle muscular dystrophy (LGMD; LGMD 1F). Using a genome-wide screen with more than 400 microsatellite markers, the authors identified a novel LGMD disease locus at chromosome 7q32.1-32.2. Within this chromosomal region, filamin C, a gene encoding actin binding protein highly expressed in muscle, was an obvious candidate gene; however, the authors did not detect any defects in filamin C or its protein product.
