• Muscle Hypotonia

  In addition, both type 1 and type 2 muscle fibers are hypotrophic and the normal pattern of myofibrillar array is lost [ 6 ]. These functional and morphological changes in postsynapses and muscle fibers cause hypotonia in patients with CDG. [jaclinicalreports.springeropen.com]

• Joint Deformity

  During adolescence or adulthood, individuals with PMM2 -CDG have reduced sensation and weakness in their arms and legs (peripheral neuropathy), an abnormal curvature of the spine ( kyphoscoliosis ), impaired muscle coordination (ataxia), and joint deformities [ghr.nlm.nih.gov]
