Overview of Gene Research
ACTA1, encoding skeletal muscle alpha-actin, forms the core of the sarcomeric thin filament in adult skeletal muscle. It is one of six highly conserved actin proteins associated with human disease [1].
Mutations in ACTA1 are a significant genetic cause of nemaline myopathy, with the vast majority (74%) of ACTA1 variants causing this disorder. However, an increasing number of variants are also linked to cardiomyopathy and novel phenotypes like distal myopathy [1]. In an in vitro model of nemaline myopathy using iPSC-derived skeletal myocytes with an ACTA1 H40Y point mutation, mitochondrial dysfunction and oxidative stress were observed as disease phenotypes, though nemaline rods were absent [2]. Clinically, the number of reported ACTA1-related disease phenotypes has grown from five to 20, and there seems to be a correlation between clinical/histological presentations and mutation positions in ACTA1-related nemaline myopathy [1,3].
In summary, ACTA1 is crucial for the normal assembly and function of the thin filament in skeletal muscle. Studies, including in vitro models, have revealed its role in muscle-related disorders such as nemaline myopathy and cardiomyopathy. Understanding ACTA1 through these research models is key to deciphering the mechanisms of these diseases and potentially developing targeted therapies.
