About HIBM

HIBM has recently been renamed GNE myopathy, but historically has also been called Quadriceps Sparing Myopathy (QSM), Inclusion Body Myopathy type 2, Distal Myopathy with Rimmed Vacuoles (DMRV) and Nonaka myopathy. HIBM is a severe, adult-onset, progressive, genetic neuromuscular disease caused by a defect in the biosynthetic pathway for sialic acid (SA). Patients with HIBM typically begin to have weakness and abnormal walking at 18 to 30 years of age. The body's failure to produce enough sialic acid causes muscles to slowly waste away and can lead to very severe disability within 10 to 20 years of diagnosis, with patients often ending up wheelchair-bound within that time. There is currently no approved therapy.
