The UMi028-A-2 human induced pluripotent stem cell line carries a homozygous mutation (rs377155188, C>G, p.S1038C) in the tetratricopeptide repeat domain 3 (TTC3) gene that was introduced via CRISPR/Cas9 genome editing. The line was originally derived from a neurologically normal male and has been thoroughly characterized following editing. The p.S1038C variant has been shown to potentially contribute to the risk of late onset Alzheimer’s disease and is a resource to further investigate the consequences of TTC3 and this alteration in disease pathology.
