Abstract excerpt
BACKGROUND: An accurate genetic diagnosis of Becker muscular dystrophy (BMD) can be sometimes challenging due to deep intronic DMD variants. Here, we report on the genetic diagnosis of a BMD patient with a novel deep-intronic splice-altering variant in DMD. METHODS: The index case was a 3.8-year-old boy who was suspected of having a diagnosis of BMD based on his clinical, muscle imaging, and pathological...
