Generation of an induced pluripotent stem cell line from a patient with global development delay carrying DYRK1A mutation (c.1730T>A) and a gene correction isogenic iPSC line.

Mental retardation autosomal dominant 7 (MRD7), or DYRK1A Related Intellectual Disability Syndrome (OMIM 614104) is a developmental syndrome with microcephaly, intellectual disability, language delay and epileptic seizures. Haploinsufficiency of DYRK1A is the cause of MRD7. Here, we generated an induced pluripotent stem cell (iPSC) line with the mutation (DYRK1Ac.1730T>A) from the Peripheral blood mononuclear cell (PBMC) of a MRD7 patient along with an isogenic gene-corrected control iPSC line by CRISPR/Cas9 genome editing. Both iPSC lines showed full pluripotency, normal karyotype and differentiation capacity without integrating vectors. These DYRK1A mutant and isogenic gene-corrected iPSC control line provides a useful model to study the underlying molecular mechanisms of MRD7.
