Key result

Among 28 Chinese patients with nemaline myopathy, clinical features showed great heterogeneity across typical congenital, childhood, and adult-onset types, with diagnosis relying on muscle biopsy.

Population

28 patients with nemaline myopathy from China, including 12 from a single hospital and 16 from literature.

Overview

Muscle biopsy remains essential amid nemaline myopathy heterogeneity; this case series leaves open generalizability and genetic insights.

Structured PICO

P
Population
28 Chinese patients with nemaline myopathy, ranging in age from 4 to 74 years, were retrospectively analyzed for clinical and pathological features.
O
Outcome
Clinical and pathological features of nemaline myopathy

Nemaline myopathy presents with significant clinical heterogeneity, and its diagnosis relies heavily on muscle biopsy revealing characteristic rods predominantly in type I fibers.

Limitations

  • Small number of patients enrolled
  • Bias for exclusion of neonatal and infantile patients
  • Small number of patients
  • Bias for exclusion of neonatal and infantile patients (missing severe and intermediate types)

Cite This Study

Yin et al. (2014) conducted an observational in Nemaline myopathy (n=28). Nemaline myopathy was evaluated. Among 28 Chinese patients with nemaline myopathy, clinical features showed great heterogeneity across typical congenital, childhood, and adult-onset types, with diagnosis relying on muscle biopsy.
