Nemaline myopathy is an inherited muscle disease that is mainly diagnosed by the presence of nemaline rods in muscle biopsies. Of the nine genes associated with the disease, five encode components of striated muscle sarcomeres.

Nemaline myopathy: A report of four cases
Nemaline myopathies are a group of genetically determined (autosomal dominant/recessive) congenital myopathies characterized by the formation of nemaline rods within muscle fibers.

Coexistence of central nucleus, cores, and rods: Diagnostic relevance
Background: Congenital myopathies (CMs) though considered distinct disorders, simultaneous occurrence of central nucleus, nemaline rods, and cores in the same biopsy are scarcely reported. Objective: A retrospective reassessment of cases diagnosed as CMs

Immunohistochemical Study of Rods in Nemaline Myopathy [PDF]
We used immunohistochemistry to study the expression of some proteins of the cytoskeleton (desmin and vimentin) and of the sarcomere (tropomyosin, myosin and actin), in muscle fibers of a patient with nemaline myopathy. Desmin, myosin and actin were present in the regions of rods but not vimentin.

Myeloma-Associated Sporadic Late-Onset Nemaline Myopathy, Successfully Treated with Daratumumab Based Induction and Autologous Stem Cell Transplantation: A Case Report. [PDF]
ABSTRACT Sporadic late‐onset nemaline myopathy (SLONM) is a rare, acquired myopathy often associated with monoclonal gammopathy. We report a 48‐year‐old man presenting with progressive proximal and truncal muscle weakness in whom SLONM associated with smoldering myeloma was highly suspected.

ACTA1-Related Adult-Onset Scapuloperoneal Myopathy With Cores and Rods. [PDF]
We report a patient with an adult‐onset, slowly progressive, ACTA1‐related scapuloperoneal myopathy with cores and rods, determined by the heterozygous variant NM_001100.4:c.1001C > T, p.(Pro334Leu). The scapuloperoneal phenotype could represent a distinct subcategory, and the characterisation of this patient with a less severe, different clinical ...

Cytoplasmic body pathology in severe ACTA1-related myopathy in the absence of typical nemaline rods. [PDF]
Mutations in ACTA1 cause a group of myopathies with expanding clinical and histopathological heterogeneity. We describe three patients with severe ACTA1-related myopathy who have muscle fiber cytoplasmic bodies but no classic nemaline rods.

Concurrent Sporadic Late-Onset Nemaline Myopathy and an Excessive Glycogen Accumulation Associated With Monoclonal Gammopathy. [PDF]
ABSTRACT Background Monoclonal gammopathy‐associated myopathies (MGAMs) include light chain (AL) amyloid myopathy, sporadic late‐onset nemaline myopathy (SLONM), and vacuolar myopathy with monoclonal gammopathy and stiffness (VAMMGAS). These subtypes usually occur separately, although rare overlap has been described. We report a patient with monoclonal

Clinical, Histological, and Genetic Characterization of a Large Cohort of 49 Patients With Nebulin-Related Congenital Myopathy. [PDF]
Congenital nemaline myopathies are rare genetic disorders that typically manifest at birth or in childhood, with muscle weakness and respiratory distress. They are characterized by the presence of rod‐like structures on the muscle biopsy, or a mix of rods with cores, focal areas with disorganization of oxidative activity. Pathogenic variants in the NEB
