Abstract |
Duchenne muscular dystrophy (DMD) is an X-linked recessive muscle-wasting disease caused by a mutation in the DMD gene. The aim of this study was to identify a de novo mutation of the DMD gene in the family of a 9-month-old Chinese male patient, as well as to describe the phenotypic characteristics of this patient. The patient was suspected to suffer from DMD according to physical examination, biochemical analyses, and electromyogram. We identified a duplication of exons 4-42 in DMD gene with targeted exome sequencing and multiplex ligation-dependent probe amplification (MLPA). In addition, the patient's mother was a carrier of the same mutation. We identified a de novo duplication of exons 4-42 in a patient with early stage DMD. The discovery of this mutation may provide insights into future investigations. |
