Key result
ARPP expression is reduced in muscular dystrophy but increased in congenital myopathies versus controls.
Why the study?
Does ARPP expression differ in skeletal muscles of patients with muscular dystrophy, congenital myopathy, and spinal muscular atrophy compared to controls?
Observational (n=39)

Evaluation of ARPP expression patterns may aid in the histological diagnosis of muscle diseases such as muscular dystrophy, congenital myopathy, and spinal muscular atrophy.

ARPP patterns may aid histological subtyping of muscle diseases; leaves open diagnostic utility without prospective validation.
Nakada et al. (2003) conducted an observational in Muscular dystrophy, congenital myopathy, and spinal muscular atrophy (n=39). Muscular dystrophy, congenital myopathy, and spinal muscular atrophy vs. Control muscle was evaluated on ARPP expression levels and distribution. ARPP expression was lower in muscular dystrophy compared to controls, but increased in congenital myopathies and distributed in groups in spinal muscular atrophy.
