Permanent myopathy caused by mutation of SCN4A Metl592Val:Observation on myogenesis in vitro and on effect of basic fibroblast growth factor on the muscle
Objective The present study is to observe in vitro the proliferation ability of the muscle cells from permanent myopathy (PM) patients of nomokalaemic periodic paralysis (normKPP),which is caused by mutations of Met1592Val in the skeletal muscle voltage gated sodium channel (SCN4A) gene on chromosome 17q23.1. We also evaluate the possible effect of the foreign basic fibroblast growth factor (bFGF) in preventing and curing PM. Methods The gastrocnemius muscle cells were taken from two male patients with PM o...

1 Introduction Nomokalaemic periodic paralysis (normKPP) is caused by mutation in the skeletal muscle voltage gated sodium chan- nel (SCN4A) gene on chromosome 17q23.1[1, 2], characterizedby transient and recurrent attacks of paralysis followed by complet
