Generation of a human induced pluripotent stem cell line (FDIBSi002-A) derived from a patient with DYRK1A syndrome carrying a heterozygous DYRK1A mutation (c.1042G>A).

DYRK1A syndrome is a neurodevelopmental disorder caused by DYRK1A haploinsufficiency. We generated a human induced pluripotent stem cell (iPSC) line, FDIBSi002-A, from a 4-year-old female patient carrying a de novo heterozygous c.1042G>A (p.G348R) mutation in DYRK1A. Peripheral blood mononuclear cells (PBMCs) were reprogrammed using non-integrating episomal vectors. The established iPSC line exhibited a normal karyotype (46, XX), expressed pluripotency markers, and demonstrated trilineage differentiation potential. This patient-specific cell line provides a valuable model for investigating the pathogenic mechanisms of DYRK1A-related intellectual disability and for drug screening.
