It is extremely rare, and only a few cases having been reported until now. Here we report four Chinese infants with fatal neuromuscular disorders characterized by abdominal and trunk skeletal muscle stiffness and rapid respiratory insufficiency progression. Electromyograms showed increased insertion activities and profuse fibrillation potentials with complex repetitive discharges. Immunohistochemistry staining of muscle biopsies showed accumulations of desmin in the myocytes. Powdery Z-bands with dense granules across sarcomeres were observed in muscle fibers using electron microscopy. All patients carry a homozygous c.3G&gt;A mutation in the CRYAB gene, which resulted in the loss of the initiating methionine and the absence of protein. This study\u2019s findings help further understand the disease and highlight a founder mutation in the Chinese population.<\/jats:p>","DOI":"10.31083\/j.jin.2021.01.267","type":"journal-article","created":{"date-parts":[[2021,4,2]],"date-time":"2021-04-02T08:54:59Z","timestamp":1617353699000},"source":"Crossref","is-referenced-by-count":4,"title":["c.3G&gt;A mutation in the CRYAB gene that causes fatal infantile hypertonic myofibrillar myopathy in the Chinese population"],"prefix":"10.31083","volume":"20","author":[{"given":"Xin-Guo","family":"Lu","sequence":"first","affiliation":[{"name":"Department of Neuromuscular Research Lab, Shenzhen Children\u2019s Hospital, 518038 Shenzhen, P.
