Myotonic Dystrophy Type 1 (DM1) Overview

Myotonic dystrophy type 1 (DM1), or Steinert disease, is a progressive, autosomal dominant multisystemic neuromuscular disorder caused by an unstable CTG trinucleotide repeat expansion in the 3′ untranslated region of the DMPK gene. This expansion leads to the nuclear retention of toxic transcript RNAs that sequester muscleblind-like (MBNL) splicing factors, inducing widespread embryonic spliceopathy across skeletal, cardiac, smooth muscle, and central nervous tissues. Patients clinically present with classic myotonia (delayed muscle relaxation), distal muscle weakness, ptosis, cataracts, early-onset balding, and severe hypoventilation. Crucially, conduction system disease creates lethal ventricular arrhythmias, making regular electrocardiographic or pacemaker surveillance mandatory. General anesthesia carries an unusually elevated risk of respiratory and cardiac collapse. Diagnosis is confirmed via targeted genetic molecular testing. Management in 2026 remains primarily supportive, utilizing mexiletine for disabling myotonia under strict cardiological monitoring, and nocturnal non-invasive ventilation for hypoventilation. However, the therapeutic landscape has transformed with advanced disease-modifying RNA-targeted candidates, including zeleciment basivarsen (DYNE-101), entering confirmatory pivotal phase 3 global evaluation.
