Explain the genetic basis for the disease in question, being sure to include a) Discussion of the defective protein being produced: C. b) Explanation of what this protein normally does, and c) Description of how this protein's dysfunction leads to cellular damage, therefore, this patient's physical issues. D. What is the prognosis for this patient? erences:Explanation / Answer
Symptoms associated with neuromusular disorders.
Myopathy is a common neuro muscular disorder due to muscle fibre dysfunctioning causing muscle weakness as primary symptom. It can be either inherited or acquired.
Duchenne muscular dystrophy usually affects the boys between the ages of 3-5. Rapidly progresses and leads to inability to walk by the age of 12. even it leads to use of respirator for breath by the age of 20.
Muscle wasting and generalized weakness occurs in limbs and trunk first causing enlarged calf muscles.
Disease have slow progress as it affects all voluntary muscles. Survival is rare beyond 20 and have poor prognosis.
genetic changes in body leading to production of faulty proteins. Dystrophin-a protein which is essential for anchoring the cytoskeleton of muscular cells to extracellular matrix, which is either limited or absent in this disease.
