Early in life the participant had typical development, but held a pen in a unique way and ran with his fingers and hands outstretched. At age 21, he began to speak in a whisper. This difficulty speaking (dysphonia) progressed for 1-2 years, but later stabilized. At age 29, the participant began to experience involuntary movements of the trunk and back and, at age 33, he began to have involuntary movements of the feet as well. The participant has abnormal eye movements (saccadic smooth pursuit), curvature of the spine (scoliosis, lumbar hyperlordosis), reduced sense of touch in his limbs (impaired distal tactile sensation), and difficulty swallowing (dysphagia). He also has rigidity and an unsteady gait.
The participant has a younger brother who has similar symptoms.
Clinicians and researchers are investigating the following genetic changes to see if they are causing the participant’s symptoms:
