This work describes the successful reprogramming of two human induced pluripotent stem cell (iPSC) lines originating from two independent ALS patients, both of whom carry a C9orf72 HRE mutation.
Abstract
The GGGGCC hexanucleotide repeat expansion (HRE) within the C9orf72 gene constitutes the leading genetic driver of amyotrophic lateral sclerosis (ALS). This fatal neurodegenerative disorder is characterized by the systematic loss of both the upper and lower motor neurons across both the central and peripheral nervous systems. This work describes the successful reprogramming of two human induced pluripotent stem cell (iPSC) lines originating from two independent ALS patients, both of whom carry a C9orf72 HRE mutation. Validation of the two established iPSC lines confirmed the expression of pluripotency markers, normal karyotypes, and successful trilineage differentiation. Consequently, these lines provide a robust in vitro platform to model ALS and study C9orf72-mediated disease mechanisms.
The generation and characterization of two induced pluripotent stem cell lines are described, one derived from an ALS patient carrying the heterozygous SQSTM1 c.1175C > T (p.Pro392Leu) mutation and another derived from a patient carrying the heterozygous TBK1 c.2402A > T (p.His801Leu) variant of unknown significance.

Two isogenic induced pluripotent stem cell lines carrying homozygous LMNA variants are generated by prime editing of a healthy donor iPSC line, providing a valuable platform for functional characterization and potential clinical reclassification of LMNA VUS.

iPSC is generated from two deletion patients (one with major depressive disorder, one with specific phobia) and three duplication patients (one with recurrent major depressive disorder, one with ADHD, one with autistic traits) to model pathogenesis in vitro.

Fabry disease is a rare genetic disease caused by loss-of-function in the GLA gene. This gene encodes the lysosomal enzyme α-galactosidase A (α-Gal A). A deficiency of α-Gal A results in the globotriaosylceramide buildup throughout the major organs, which is associated with increased mortality from cardiac disease in p...

The peripheral blood mononuclear cells from a patient carrying frameshift mutation in the KMT2D gene were reprogrammed using the CytoTune-iPS2.0 Sendai Reprogramming Kit to allow proper in vitro disease modelling of Kabuki syndrome 1.
Comparative studies using induced pluripotent stem cells (iPSCs) from patients with those from healthy individuals as controls are flawed by genetic background contribution to disease phenotype. Here, we used precise gene editing to generate gene-corrected isogenic control lines for a single pathogenic variant in the U...
