There are several associated symptoms that can be observed in such patients including but not limited to a delay in walking and sitting, difficulty in breathing and heart failure. These symptoms are found as a result of the inability to synthesize dystrophin and associate protein complexes that leave muscles weak and unable to repair any damaged sustained.
Patients experiencing these conditions often exhibit delays in walking and sitting, struggle with breathing, and may develop heart failure. This is due to a lack of dystrophin and the resulting inability to form proper protein complexes that support muscle health and repair.
