A number of mutations in the human TBX5 gene have been described which cause Holt-Oram syndrome, a severe congenital disease associated with abnormalities in heart and upper limb development. We have used a prime-editing approach to introduce a patient-specific disease-causing TBX5 mutation (c.920_C > A) into an induced pluripotent stem cell (iPSC) line from a healthy donor. The resulting iPSC line provides a powerful tool to identify and analyze the biological and molecular impact of this specific TBX5 mutation in comparison to the isogenic control iPSC line during cardiac development.
