Derivation of induced pluripotent stem cell from a Baraitser-Winter Cerebrofrontofacial syndrome with ACTB mutation

Baraitser-Winter Cerebrofrontofacial syndrome (BWCFF, OMIM: 243310) is a rare congenital developmental disorder marked by distinct facial dysmorphisms, coloboma, diminutive stature, and cognitive impairment, as initially described by Baraitser and Winter in 1988. Here, we derived human induced pluripotent stem cells (hiPSCs) from a 4-year-old male patient diagnosed with Baraitser-Winter Cerebrofrontofacial syndrome and harbouring a mutation in the ACTB gene. The newly established hiPSC line exhibited normal karyotypes and demonstrated the capacity to differentiate into all three germ layers. Additionally, these hiPSCs maintained their original genotype and expressed markers of pluripotency. Patient-derived hiPSCs would serve as a valuable tool for in vitro modelling of Baraitser-Winter Cerebrofrontofacial syndrome and reveal the potential pathogenesis induced by ACTB gene mutations.
