Myopathy mutations in alpha-skeletal-muscle actin cause a range of molecular defects.

Abstract excerpt

Mutations in the gene encoding alpha-skeletal-muscle actin, ACTA1, cause congenital myopathies of various phenotypes that have been studied since their discovery in 1999. Although much is now known about the clinical aspects of myopathies resulting from over 60 different ACTA1 mutations, we have very little evidence for how mutations alter the behavior of the actin protein and thus lead to disease. We used a...
