1. Sunny

2.  Gradual weakening of muscle  1 in 3,500 male infants

3.  X-linked recessive  Gene that codes for dystrophin (Keeps muscle cells together by maintaining the cell structure)

5.  Muscle weakness- beginning from lower limbs  Wasting- loss of muscle  Delay of ability of walking  Frequent falls  Have difficulty of getting up from the ground  Psuedohypertophy- bigger calves  Learning difficulty

7.  Bones develop abnormally  Breathing problems Caused by deformed bones and muscle weakness  Cardiomyopathy  Life expectancy: 27 Death due to breathing problems and heart problems

8.  Genetic test Use blood sample -find major change(insertion, deletion) -code out the gene for making dystrophin  Blood test High levels of creatine kinase(usually concentrated in muscle cell) in blood  Muscle Biopsy Absence of dystrophin in muscle

9.  No cure  Steroids- maintain muscle function and slow muscle weakening  Physical therapy- maintain muscle strength  Assisted Ventilation  Surgeries  Cardiac transplantation
