Polyneuropathy associated with IgM monoclonal gammapathy with anti-MAG

MONDO:0018977

Polyneuropathy associated with IgM monoclonal gammapathy (MG) with anti-MAG (myelin-associated-glycoprotein) activity is a demyelinating polyneuropathy characterized clinically by sensory ataxia, tremor, paresthesia, and impaired gait.

Also known as: anti-MAG neuropathy, neuropathy associated with monoclonal IgM antibodies to myelin-associated glycoprotein

Ultrasound probes nerve stiffness in rare nerve diseases

Knowledge-focused Completed

Researchers at Nantes University Hospital are studying whether nerves feel stiffer in people with three rare peripheral neuropathies: CIDP, CMT1a, and anti-MAG neuropathy. They use ultrasound shear wave elastography to measure nerve stiffness in 36 participants aged 18 to 65 and …
