Abstract
Gracia-Diaz and colleagues analyzed high-density DNA microarray and whole-genome sequencing (WGS) data from the KOLF2.1J “reference” human induced pluripotent stem cell (hiPSC) line1 and report the presence of five high-confidence heterozygous copy number variants (CNVs) at least 100 kbp in length.2 Since three of these CNVs span coding genes, some of which have been associated with neurodevelopmental disease, the authors raise the concern that these CNVs may compromise the utility of KOLF2.1J for neurological disease modeling.
