Congenital myotonic dystrophy (CDM) is a genetic disease caused by an abnormally long CTG repeat expansion in the DMPK gene, which generally increases in size following intergenerational transmission. CDM is the rarest and most severe form of myotonic dystrophy type 1, yet an important number of patient-derived cells are needed to study this heterogeneous disease. Therefore, we have reprogrammed lymphoblastoid cells derived from a 3-year-old male with CDM into induced pluripotent stem cells (iPSCs; CBRCULi015-A) featuring 1800 CTG repeats and characterized their pluripotent state. This cell line constitutes an important resource to study CDM and potential treatments in vitro.
