1 Muscular Dystrophy Kate DeAngelis AP Biology 1/6/09 Kate DeAngelis AP Biology 1/6/09 Charles DeAngelis:

2 Intro to Muscular Dystrophy / Aka: MD or inherited myopathy / Discovered by: Sir Charles Bell in 1830. / Aka: MD or inherited myopathy / Discovered by: Sir Charles Bell in 1830.

3 Mode of Inheritance / X-linked recessive: trait is carried on one of the two-paired genes on the X chromosome / Duchenne MD / Autosomal recessive: both parents must be carriers of the affected gene / Type 2 Limb-girdle MD / Congenital MD / Autosomal dominant: carrier of one affected gene will manifest the trait / Type 1 Limb-girdle MD / Myotonic dystrophy / And others / X-linked recessive: trait is carried on one of the two-paired genes on the X chromosome / Duchenne MD / Autosomal recessive: both parents must be carriers of the affected gene / Type 2 Limb-girdle MD / Congenital MD / Autosomal dominant: carrier of one affected gene will manifest the trait / Type 1 Limb-girdle MD / Myotonic dystrophy / And others

4 Clinical Description / Muscle weakness; apparent lack of coordination; progressive crippling / Frequent falls; large calf muscles; difficulty getting up from lying down; waddling gait; mild mental retardation / Most commonly found in males / Some cases are fatal / Muscle weakness; apparent lack of coordination; progressive crippling / Frequent falls; large calf muscles; difficulty getting up from lying down; waddling gait; mild mental retardation / Most commonly found in males / Some cases are fatal

5 Treatment / Exercise and strength conditioning / Medications used to help manage muscle spasms and pain / Assistive devices / Walkers / Canes / Wheelchair / Surgery: release the contractures that may develop / Not cure yet :( / Exercise and strength conditioning / Medications used to help manage muscle spasms and pain / Assistive devices / Walkers / Canes / Wheelchair / Surgery: release the contractures that may develop / Not cure yet :(

6 Detection / Genetic counseling / Muscle biopsies / Electromyography or nerve conduction tests / Blood enzyme tests / Genetic counseling / Muscle biopsies / Electromyography or nerve conduction tests / Blood enzyme tests

7 Legal Issues / Some cases are fatal / Physicians may be biased to certain treatments / Most treatments improve the quality of the patients life, but do not prevent loss of muscle function / Some cases are fatal / Physicians may be biased to certain treatments / Most treatments improve the quality of the patients life, but do not prevent loss of muscle function
