Generation and characterization of a human iPSC line and gene-corrected isogenic line derived from a patient with a CELF2 gene mutation

The identification of neurodevelopmental defects in a patient harboring a heterozygous de novo missense variant (NM_006561.4, c.1517G > A, p.Arg506His) within the CELF2 gene. Here, we describe the establishment of a patient-derived induced pluripotent stem cell (iPSC) line, alongside an isogenic gene-corrected iPSC line, achieved through CRISPR/Cas9 genome editing. These lines exhibit the expression of pluripotency markers, demonstrate differentiation potential into all three germ layers, and maintain a normal karyotype. These iPSC lines serve as valuable tools for investigating the consequences of CELF2 related neurodevelopmental disorders.
