Generation of two induced pluripotent stem cell lines with heterozygous and homozygous amyotrophic lateral sclerosis-causing mutation P525L (c.1574C > T) in FUS gene.

Mutations in the FUS (fused in sarcoma) gene are implicated in the neurodegenerative disease amyotrophic lateral sclerosis (ALS). However, the pathophysiology underlying these mutations remains elusive. In this study, we created two induced pluripotent stem cell (iPSC) lines through genetic modification of a healthy hiPSC line (WTC11, UCSFi001-A). These iPSC lines carry the heterozygous and homozygous P525L (c.1574C > T) mutation in the FUS gene. We confirmed that both cell lines possess typical stem cell morphology, normal karyotype, and pluripotency. Our iPSC lines offer a valuable resource for investigating the pathological mechanisms underlying the FUS mutation P525L in ALS.

Generation of two induced pluripotent stem cell lines with heterozygous and homozygous amyotrophic lateral sclerosis-causing mutation R521G (c.1561C > G) in FUS gene.

Mutations in the RNA-binding protein FUS (fused in sarcoma) are linked to amyotrophic lateral sclerosis (ALS), but the pathogenesis is not fully understood. For modeling ALS, here we generated two induced pluripotent stem cell (iPSC) lines carrying the heterozygous and homozygous R521G (c.1561C > G) mutation in the FUS gene via genetic modification of a healthy hiPSC line (WTC11, UCSFi001-A). Both lines show normal stem cell morphology and karyotype, express pluripotent markers, and can differentiate into three germ layers, providing a valuable resource in determining the pathological mechanisms underlying the FUS mutation of R521G in ALS.
