ABSTRACT

DOK7-related Congenital Myasthenic Syndrome (CMS) is a rare genetic neuromuscular junction disorder. This is one of the most common of the recessive forms of CMS, often presenting with more static proximal weakness (hence also referred to as limb girdle CMS). Whole-genome sequencing of affected patients implicates frameshift duplication mutations in DOK7 as drivers of impaired neuromuscular-junction signaling. In this study, we generated a human induced pluripotent stem cell (hiPSC) line TRNDi045-A-38 from the KOLF2.1J reference line, engineered to carry homozygous DOK7 c.1124_1127dupTGCC mutation knock-in using CRISPR/Cas9. This iPSC line could be used for in vitro disease modeling to study disease pathophysiology and for therapeutic development.
