GNE Myopathy Overview

GNE myopathy—historically referred to as hereditary inclusion body myopathy (HIBM) or distal myopathy with rimmed vacuoles (DMRV)—is a rare, autosomal recessive, progressive neuromuscular disorder caused by biallelic mutations in the GNE gene. This gene encodes a critical bifunctional enzyme responsible for the rate-limiting step in sialic acid biosynthesis; its deficiency drives the profound hyposialylation of vital muscle glycoproteins, ultimately leading to myofiber degeneration. Clinically, the disease typically manifests in early adulthood (the second or third decade of life) with distal lower extremity weakness, most commonly presenting as bilateral foot drop. As the disease relentlessly progresses to involve proximal lower and upper extremity musculature, it exhibits a unique, pathognomonic clinical and radiographic hallmark: the pronounced and sustained sparing of the quadriceps femoris muscles, even in the advanced stages of severe ambulatory impairment. Diagnosis is suspected based on this classic phenotypic pattern combined with a muscle biopsy revealing characteristic rimmed vacuoles in the absence of primary inflammation, and is definitively confirmed via targeted molecular genetic testing. Because there are currently no approved disease-modifying therapies—following the clinical trial failures of oral sialic acid substrate replenishment strategies—the standard of care remains strictly supportive and multidisciplinary, prioritizing targeted physical therapy, custom orthotics (such as ankle-foot orthoses), and advanced mobility aids, while research heavily pivots toward investigational adeno-associated virus (AAV)-mediated gene therapies.
