Identification of a new SYT2 variant validates an unusual distal motor neuropathy phenotype.

Objective: To report a new missense mutation causing distal hereditary motor neuropathy and presynaptic neuromuscular junction (NMJ) transmission dysfunction.

Methods: We report a multigenerational family with a new missense mutation, c. 1112T>A (p.

Risk of hematoma following needle electromyography of the paraspinal muscles.

The purpose of this study was to establish the incidence of MRI-detectable hematomas following paraspinal EMG. We provide a retrospective review of patients who underwent paraspinal EMG and subsequent concordant level spine MRI. A total of 370 charts (431 MRIs) met the inclusion criteria.
