Cytoplasmic body pathology in severe ACTA1 -related myopathy in the absence of typical nemaline rods

Highlights • ACTA1 -myopathy can present with cytoplasmic bodies in the absence of nemaline rods. • p.Asn94Lys ACTA1 mutation may be linked to this pathology and severe phenotype. • ACTA1 mosaicism may masquerade as recessive inheritance, complicating the workup.
