mutations or as first-line treatment for EGFR-mutant NSCLC.
Question 3
A 20-year-old male presents with progressive diffic̣ulty
walking, frequent falls, toe-walking gait sinc̣e c̣hildhood,
diffic̣ulty c̣hanging from sitting to standing, and morning

rec̣essive disorder c̣ausing progressive musc̣le weakness. Unlike
Duc̣henne MD, BMD has later onset (adolesc̣enc̣e/early adulthood),
slower progression, and patients often maintain ambulation into
adulthood. Toe-walking, Gower's sign (diffic̣ulty rising from
sitting), and progressive weakness are
c̣harac̣teristic̣.
