Key result
Transgenic mice expressing approximately equal proportions of mutant ACTA1(D286G) and wild-type actin presented with severe immobility and structural muscle abnormalities requiring euthanasia.
The study provides the first experimental evidence that mutant protein load determines the severity of ACTA1 disease, suggesting that altering this ratio could be a therapeutic strategy.

Mutant load may drive ACTA1 severity in mice; leaves open whether ratio modulation offers a translatable therapeutic strategy.
Ravenscroft et al. (2011) studied Dominant ACTA1 disease. Transgenic expression of ACTA1(D286G) vs. Wild-type mice was evaluated on Disease severity and survival. Transgenic mice expressing approximately equal proportions of mutant ACTA1(D286G) and wild-type actin presented with severe immobility and structural muscle abnormalities requiring euthanasia.
