Establishment of (Juctci007-A) Ipsc Line from a Patient with Congenital Myasthenic Syndrome (CMS) Carrying a Homozygous Mutation P.arg331trp (c.991c > T) in the CHRNE Gene.

Induced pluripotent stem cells (iPSCs) were generated from skin fibroblasts obtained from a 24-year-old female diagnosed with hereditary congenital myasthenic syndrome (CMS), caused by p.Arg331Trp (c.991C > T) homozygous mutation in the gene coding for the epsilon subunit of the acetylcholine receptor (CHRNE). The generated iPSCs shared similar karyotype with the parental dermal fibroblast cells, expressed pluripotency stem cell markers, and demonstrated differentiation potential into the three germ layers. This cell line can be used as an ideal model to facilitate the understanding of the pathogenic disease mechanisms underlying the congenital myasthenic syndrome and for developing novel therapeutic strategies.
