The linkage relationships of the gene for Emery-Dreifuss muscular dystrophy have been analysed in a large American kindred using DNA probes from different regions of the X chromosome. Close linkage was found with the locus for factor VIII, with no recombinants in 12 opportunities (maximum lod score 4.3), and with locus DXS15 (two recombinants in 17 opportunities, maximum lod score 2.9 at 0 = 10...

This report describes a family showing muscular dystrophy and atrioventricular block with an x-linked hereditary transmission. Among a known pedigree of 101 family members, 12 males were found to have skeletal muscle involvement and six needed pacemakers around age 30 years. Unlike the x-linked muscular dystrophies of Duchenne and of Becker, the predominant skeletal involvement was in humeral m...

BACKGROUND There is a marked variation in clinical phenotypes that have been associated with mutations in FKRP, ranging from severe congenital muscular dystrophies to limb-girdle muscular dystrophy type 2I (LGMD2I). METHODS We screened the FKRP gene in two cohorts totaling 87 patients with the LGMD phenotype. RESULTS The c.826C>A, p.L276I mutation was present in six patients and a compound ...

Neuromuscular diseases can have a tremendous impact on pregnant women and affect offspring. Healthcare providers need to have a firm understanding of the genetics involved as well as the potential complications that can arise when treating pregnant women who have been diagnosed with a neuromuscular disease or have an increased risk for delivering an infant affected by one of these disorders. Th...
