( the prevalence of this mutation is 5p...)Scientists detect probable genetic cause of some Parkinson's disease cases

the prevalence of this mutation is 5 percent in families with a history of the disease and it is relatively common even among those without a family history, it's possible that detecting this mutation will help identify people at increased risk for Parkinson's disease." About 50,000 Americans are diagnosed with Parkinson's disease each year. The disease occurs when certain nerve cells die or become impaired and can no longer produce dopamine, a brain signaling chemical (neurotransmitter). Without it, individuals can develop tremor or trembling in hands, arms, legs, jaw, and face; rigidity or stiffness of the limbs and trunk; bradykinesia, or slowness of movement; and postural instability or impaired balance and coordination. Patients may also have difficulty walking, talking, or completing other simple tasks. The disease is both chronic and progressive. Incidence of the disease increases with age, with an average onset at about 60 years.
