This disorder can be inherited in an autosomal dominant ( Thomsen disease ; sometimes associated with reduced penetrance ) or recessive ( Becker disease ; OMIM 255700) fashion. Thomsen disease is rare and exhibits a high degree of genetic heterogeneity. %K Genetic testing %K Neuromuscular disease %~
